2018 has been Bezos' year after he was officially named the richest person in the world and Amazon was named the second most valuable company. Only Apple ranks higher, CNBC reported.

Bezos is said to have come up with the idea of an online bookstore when he was 30, The Daily Mail reported. At the time, the internet was growing at 2,300 percent a year. He was working at a hedge fund in New York, and despite the stability that his boss and the job offered, Bezos, with the urging of his wife, MacKenzie, decided to launch his idea. The rest, they say, is history, as his dream of an online bookstore launched in 1994 and has evolved into an online retailer that threatens top seller Walmart, CNBC reported.

But selling books isn’t Bezos’ only focus.

He founded Blue Origin, a private space flight company that will offer space tourism. Amazon also is at the forefront of the cloud storage. Companies such as Netflix and government organizations such as the CIA use Amazon's storage through cloud services, CNN reported. In 2013, Bezos moved from books to newspapers when he bought The Washington Post for $250 million. Amazon doesn't own the iconic paper; Bezos himself does, CNN reported.
