Life is too short and there are only a few people who know how to take full advantage of it and Bill Gates was one of them. He was the second child of a middle-class family. As he grew up he became interested in writing computer programmes because he was very much fascinated by what computers can do if they are programmed the right way and of course he was smart enough to realize the money-making opportunity behind it. So, Bill Gates with his school friend Allen started a programming business called Microsoft. And after some time finally, they got a golden chance to write an operating system for IBM called "MS-DOS". And as time goes by Microsoft launched the worlds most used Operating System "Windows". Bill Gates became the richest man on earth. Since, he was an intelligent person he realized that money is that the only thing we are in this world to get but helping others and taking others to the top with us is the most important thing and then with his money, he started to focus on charity.
