As a child Elon Musk was constantly bullied. He was a dreamy, geeky guy who kept dreaming of space travel, robots, electric cars, and life on other planets. But no amount of laughter and derision could deter him. When he grew up, he was determined to make these dreams come true.

People thought he was crazy, but Musk was determined to make his dreams come true. He studied hard, he worked crazy hours. He spent long days solving problems in math and physics. He spent long nights on factory floors. 

And in the end he changed the world, becoming the richest man on earth in the process.
