He was born in time when learning programming itself was big challenge.

By age of 13, Bill showed deep interest in coding. He used to dig through the codes from trash cans of the computer centres and studies those.

At school, he met Paul Allen and they bonded over a common interest in computers.

Soon, they began skipping classes to work in school's computer room.

One day, Gates saw a new computer on the cover of a magazine that just came out in the market. Bill knew that it was an opportunity of a lifetime to build a software for them before anyone else did.

So, Bill called that company and told them that he had a software ready for their computer. But it was just to gain their interest and he had not written even a single line of code for that.

His passion and belief in his skills was so much that he was willing to risk his future at Harvard for that opportunity.

Gates and Allen than dropped out of Harvard and coded the whole software in a few weeks.

It evolved into Microsoft windows which took over the whole world making Gates a billionaire at 31.

Today, Bill Gates is the richest man in the world and has net worth of 90 billion.

His story teaches us that do not be afraid to fail, be afraid not to try.
