Chetan bhagat's speech @ Symbiosis pune worth reading

Good Morning everyone and thank you for giving me this chance to speak to you. This day is about you. You, who have come to this college, leaving the comfort of your homes (or in some cases discomfort), to become something in your life. I am sure you are excited. There are few days in human life when one is truly elated. The first day in college is one of them. When you were getting ready today, you felt a tingling in your stomach. What would the auditorium be like, what would the teachers be like, who are my new classmates - there is so much to be curious about. I call this excitement, the spark within you that makes you feel truly alive today. Today I am going to talk about keeping the spark shining. Or to put it another way, how to be happy most, if not all the time.
Where do these sparks start? I think we are born with them. My 3-year old twin boys have a million sparks. A little Spiderman toy can make them jump on the bed. They get thrills from creaky swings in the park. A story from daddy gets them excited. They do a daily countdown for birthday party – several months in advance – just for the day they will cut their own birthday cake.
I see students like you, and I still see some sparks. But when I see older people, the spark is difficult to find. That means as we age, the spark fades. People whose spark has faded too much are dull, dejected, aimless and bitter. Remember Kareena in the first half of Jab We Met vs the second half? That is what happens when the spark is lost. So how to save the spark?

People whose spark has faded too much are dull, dejected, aimless and bitter. Remember Kareena in the first half of Jab We Met vs the second half? That is what happens when the spark is lost. So how to save the spark?
To nurture, always have goals. It is human nature to strive, improve and achieve full potential. In fact, that is success. It is what is possible for you. It isn't any external measure - a certain cost to company pay package, a particular car or house.
Most of us are from middle class families. To us, having material landmarks is success and rightly so. When you have grown up where money constraints force everyday choices, financial freedom is a big achievement. But it isn't the purpose of life. If that was the case, Mr. Ambani would not show up for work. Shah Rukh Khan would stay at home and not dance anymore. Steve Jobs won't be working hard to make a better iPhone, as he sold Pixar for billions of dollars already. Why do they do it? What makes them come to work everyday? They do it because it makes them happy. They do it because it makes them feel alive. Just getting better from current levels feels good. If you study hard, you can improve your rank. If you make an effort to interact with people, you will do better in interviews. If you practice, your cricket will get better. You may also know that you cannot become Tendulkar, yet. But you can get to the next level. Striving for that next level is important.
Nature designed with a random set of genes and circumstances in which we were born. To be happy, we have to accept it and make the most of nature's design. Are you? Goals will help you do that. I must add, don't just have career or academic goals. Set goals to give you a balanced, successful life. I use the word balanced before successful. Balanced means ensuring your health, relationships, mental peace are all in good order.
There is no point of getting a promotion on the day of your breakup. There is no fun in driving a car if your back hurts. Shopping is not enjoyable if your mind is full of tensions.
You must have read some quotes - Life is a tough race, it is a marathon or whatever. No, from what I have seen so far, life is one of those races in nursery school, where you have to run with a marble in a spoon kept in your mouth. If the marble falls, there is no point coming first. Same with life, where health and relationships are the marble. Your striving is only worth it if there is harmony in your life. Else, you may achieve the success, but this spark, this feeling of being excited and alive, will start to die.
One last thing about nurturing the spark - don't take life seriously. One of my yoga teachers used to make students laugh during classes. One student asked him if these jokes would take away something from the yoga practice. The teacher said - don't be serious, be sincere. This quote has defined my work ever since. Whether its my writing, my job, my relationships or any of my goals. I get thousands of opinions on my writing everyday. There is heaps of praise, there is intense criticism. If I take it all seriously, how will I write? Or rather, how will I live? Life is not to be taken seriously, as we are really temporary here. We are like a pre-paid card with limited validity. If we are lucky, we may last another 50 years. And 50 years is just 2,500 weekends. Do we really need to get so worked up? It's ok, bunk a few classes, goof up a few interviews, fall in love. We are people, not programmed devices.
I've told you three things - reasonable goals, balance and not taking it too seriously that will nurture the spark. However, there are four storms in life that will threaten to completely put out the flame. These must be guarded against. These are disappointment, frustration, unfairness and loneliness of purpose.
Disappointment will come when your effort does not give you the expected return. If things don't go as planned or if you face failure. Failure is extremely difficult to handle, but those that do come out stronger. What did this failure teach me? is the question you will need to ask. You will feel miserable. You will want to quit, like I wanted to when nine publishers rejected my first book. Some IITians kill themselves over low grades – how silly is that? But that is how much failure can hurt you. But it's life. If challenges could always be overcome, they would cease to be a challenge. And remember - if you are failing at something, that means you are at your limit or potential. And that's where you want to be.
Disappointment' s cousin is frustration, the second storm. Have you ever been frustrated? It happens when things are stuck. This is especially relevant in India. From traffic jams to getting that job you deserve, sometimes things take so long that you don't know if you chose the right goal. After books, I set the goal of writing for Bollywood, as I thought they needed writers. I am called extremely lucky, but it took me five years to get close to a release. Frustration saps excitement, and turns your initial energy into something negative, making you a bitter person. How did I deal with it? A realistic assessment of the time involved – movies take a long time to make even though they are watched quickly, seeking a certain enjoyment in the process rather than the end result – at least I was learning how to write scripts, having a side plan – I had my third book to write and even something as simple as pleasurable distractions in your life - friends, food, travel can help you overcome it. Remember, nothing is to be taken seriously. Frustration is a sign somewhere, you took it too seriously.
Unfairness - this is hardest to deal with, but unfortunately that is how our country works. People with connections, rich dads, beautiful faces, pedigree find it easier to make it – not just in Bollywood, but everywhere. And sometimes it is just plain luck. There are so few opportunities in India, so many stars need to be aligned for you to make it happen. Merit and hard work is not always linked to achievement in the short term, but the long term correlation is high, and ultimately things do work out. But realize, there will be some people luckier than you. In fact, to have an opportunity to go to college and understand this speech in English means you are pretty damm lucky by Indian standards. Let's be grateful for what we have and get the strength to accept what we don't. I have so much love from my readers that other writers cannot even imagine it. However, I don't get literary praise. It's ok. I don't looklike Aishwarya Rai, but I have two boys who I think are more beautiful than her. It's ok. Don't let unfairness kill your spark.
Finally, the last point that can kill your spark is isolation. As you grow older you will realize you are unique. When you are little, all kids want Ice cream and Spiderman. As you grow older to college, you still are a lot like your friends. But ten years later and you realize you are unique. What you want, what you believe in, what makes you feel, may be different from even the people closest to you. This can create conflict as your goals may not match with others. . And you may drop some of them. Basketball captains in college invariably stop playing basketball by the time they have their second child. They give up something that meant so much to them. They do it for their family. But in doing that, the spark dies. Never, ever make that compromise. Love yourself first, and then others.
There you go. I've told you the four thunderstorms - disappointment, frustration, unfairness and isolation. You cannot avoid them, as like the monsoon they will come into your life at regular intervals. You just need to keep the raincoat handy to not let the spark die.
I welcome you again to the most wonderful years of your life. If someone gave me the choice to go back in time, I will surely choose college. But I also hope that ten years later as well, your eyes will shine the same way as they do today. That you will Keep the Spark alive, not only through college, but through the next 2,500 weekends. And I hope not just you, but my whole country will keep that spark alive, as we really need it now more than any moment in history. And there is something cool about saying - I come from the land of a billion sparks.
Thank You.
Chetan Bhagat

Last digit lesson 3

Contd. from the last post......
Case 2: If r=0 i.e. Power is divisible by 4.
Then write it as

A4

and get the answer.
Example:

312348

Now 12348 is divisible by 4. So, the original expression reduces to

34

i.e. 81 i.e. 1

Last digit/unit place Lesson 2

In the previous lesson, the sum was easy nut to crack. Now i am coming to the original beauty of the CAT by following sum.
Question: Wht is the unit digit of

AB


Ans: Follow the following Algorithm:
Divide the B by4. Get the remainder (say) r.Obviously r=0,1,2,3. (i.e. o≤r<4)
I am taking 2 cases:-
Case 1: 0< r<4 r="1,2,3
Then the original sum reduces to

Ar

which one can find easily.

Example: What is the unit digit of

326021983


Divide 26021983 by 4. Remainder is 3. So, the sum becomes

33

and the ans. is 27 i.e. 7. .............Continued in next lesson..........

Unit place/last digit lesson 1

Question 1: What is the unit place of Expression 2345*1996?

Ans.: We'll consider only the unit digit of 2345 and 1996 i.e. 5 and 6 respectively.Hence the unit digit becomes 5*6=0
(I am taking * as multiplication.)

Be Polite? Everyone you meet is fighting a hard battle...Nice !!

REAL story ...A gossip between a Soldier and Software Engineer in Shatabdi Train

Vivek Pradhan was not a happy man. Even the plush comfort of the air-conditioned compartment of the Shatabdi express could not cool his frayed nerves. He was the Project Manager and still not entitled to air travel. It was not the prestige he sought, he had tried to reason with the admin person, it was the savings in time. As PM, he had so many things to do!!He opened his case and took out the laptop, determined to put the time to some good use."Are you from the software industry sir," the man beside him was staring appreciatively at the laptop. Vivek glanced briefly and mumbled in affirmation, handling the laptop now with exaggerated care and importance as if it were an expensive car."You people have brought so much advancement to the country, Sir. Today everything is getting computerized. ""Thanks," smiled Vivek, turning around to give the man a look. He always found it difficult to resist appreciation. The man was young and well built like a sports man. He looked simple and strangely out of place in that little lap of luxury like a small town boy in a prep school. He probably was a railway sportsman making the most of his free traveling pass."You people always amaze me," the man continued, "You sit in an office and write something on a computer and it does so many big things outside."Vivek smiled deprecatingly. Naiveness demanded reasoning not anger. "It is not as simple as that my friend. It is not just a question of writing a few lines. There is alot of process that goes behind it."For a moment, he was tempted to explain the entire Software Development Lifecycle but restrained himself to a single statement. "It is complex, very complex.""It has to be. No wonder you people are so highly paid," came the reply.This was not turning out as Vivek had thought. A hint of belligerence crept into his so far affable, persuasive tone. Everyone just sees the money. No one sees the amount of hard work we have to put in. Indians have such a narrow concept of hard work. Just because we sit in an air-conditioned office, does not mean our brows do not sweat. You exercise the muscle; we exercise the mind and believe me that is no less taxing." He could see, he had the man where he wanted, and it was time to drive home the point."Let me give you an example. Take this train. The entire railway reservation system is computerized. You can book a train ticket between any two stations from anyof the hundreds of computerized booking centres across the country. Thousands of transactions accessing a single database, at a time concurrently; data integrity, locking, data security. Do you understand the complexity in designing and coding such a system?"The man was awestuck; quite like a child at a planetarium. This was something big and beyond his imagination."You design and code such things." "I used to," Vivek paused for effect, "but now I am the Project Manager.""Oh!" sighed the man, as if the storm had passed over, "so your life is easy now."This was like the last straw for Vivek. He retorted,"Oh come on, does life ever get easy as you go up the ladder. Responsibility only brings more work. Design and coding ! That is the easier part. Now I do not do it, but I am responsible for it and believe me, that is far more stressful. My job is to get the work done in time and with the highest quality. To tell you about the pressures, there is the customer at one end, always changing his requirements, the user at the other, wanting something else, and your boss, always expecting you to have finished it yesterday."Vivek paused in his diatribe, his belligerence fading with self-realisation. What he had said, was not merely the outburst of a wronged man, it was the truth. And oneneed not get angry while defending the truth. "My friend," he concluded triumphantly, "you don't know what it is to be in the Line of Fire". The man sat back in his chair, his eyes closed as if in realization. When he spoke after sometime, it was with a calm certainty that surprised Vivek."I know sir,..... I know what it is to be in the Line of Fire......"He was staring blankly, as if no passenger, no train existed, just a vast expanse of time."There were 30 of us when we were ordered to capture Point 4875 in the cover of the night. The enemy was firing from the top. There was no knowing where the next bullet was going to come from and for whom. In the morning when we finally hoisted the tricolour at the top only 4 of us were alive.""You are a...?""I am Subedar Sushant from the 13 J&K Rifles on duty at Peak 4875 in Kargil. They tell me I have completed my term and can opt for a soft assignment. But, tell me sir, can one give up duty just because it makes life easier. On the dawn of that capture, one of my colleagues lay injured in the snow, open to enemy fire while we were hiding behind a bunker. It was my job to go and fetch that soldier to safety. But my captain sahib refused me permission and went ahead himself. He said that the first pledge he had taken as a Gentleman Cadet was to put the safety and welfare of the nation foremost followed by the safety and welfare of the men he commanded... ....his own personal safety came last always and every time."
"He was killed as he shielded and brought that injured soldier into the bunker. Every morning thereafter, as we stood guard, I could see him taking all those bullets,which were actually meant for me . I know sir....I know, what it is to be in the Line of Fire."Vivek looked at him in disbelief not sure of how to respond. Abruptly, he switched off the laptop. It seemed trivial, even insulting to edit a Word document in the presence of a man for whom valour and duty was a daily part of life; valour and sense of duty which he had so far attributed only to epical heroes. The train slowed down as it pulled into the station, and Subedar Sushant picked up his bags to alight."It was nice meeting you sir."Vivek fumbled with the handshake. This hand... had climbed mountains, pressed the trigger, and hoisted the tricolour. Suddenly, as if by impulse, he stood up at attention and his right hand went up in an impromptu salute. It was the least he felt he could do for the country.

PS: The incident he narrated during the capture of Peak 4875 is a true-life incident during the Kargil war. Capt. Batra sacrificed his life while trying to save one of the men he commanded, as victory was within sight. For this and various other acts of bravery, he was awarded the Param Vir Chakra, the nation's highest military award....

A Very Good question

I Dont need only Ans. bt a very good shortcut.
*******Suppose, the seed of any positive integer n is defined as follows:
seed(n)= n, if n<10
=seed (s(n)), otherwise,
where s(n) indicates the sum of digits of n. for example,
seed(7) = 7, seed (248) = seed(2+4+8) = seed (14) = seed (1+4) = seed (5) = 5 etc.
How many positive integers n, such that n<500, will have
a. seed(n) =9
b. seed(n) = 0
c. seed(n) = 1
