Elon Musk is now the richest man in world history, with an estimated worth of $271 billion. That’s 271 followed by nine zeros, or, to put it another way, more than the net worth of Bill Gates and Warren Buffett combined. Much of Musk’s wealth comes from his companies Tesla and SpaceX, but not all of it. In fact, a sizable chunk was obtained thanks to Musk’s shrewd lifestyle choices and good, old-fashioned luck.

Recently I sat down with Musk to discuss his wealth-accumulation strategies. Snippets of that conversation are below. A full transcript of the conversation could have been found on my Web site had my phone battery not died.
