Elon Musk lives what most would consider an insanely intense life.

He's currently a self-made billionaire 15 times over. And at 46, he's the CEO of both electric carmaker Tesla and space exploration company SpaceX. He's also the co-founder and chairman of artificial intelligence research non-profit OpenAI. In just the last year, he started Neuralink to merge humans with machine interfaces and launched The Boring Company to dig tunnels under the ground and reduce traffic woes.
