Amazon founder Jeff Bezos is on cloud nine these days . He has regained the crown as the richest person on the planet. And the reason for this is courtesy his company – Amazon. It has became the second US firm to hit a trillion-dollar value on the stock market.

Amazon’s share price has climbed during the year, lifting the personal wealth of the company’s 54-year-old founder with it. Forbes estimated his net worth about $166 billion.

Amazon’s surge has now put in on line to take over from another giant apple in the days ahead. Apple took almost 38 years as a public company to achieve the trillion dollar milestone, Amazon got there in 21 years. So the race has just begun for the top slot.

He has gone on record with a formula for success that includes taking bold bets, riding change and rebounding from setbacks.

“You need to be nimble and robust so you need to be able to take a punch and you also need to be quick and innovative and do new things at a higher speed, that’s the best defense against the future,” Bezos said in an interview published in Vanity Fair magazine last year.
