If you want to perform at the absolute limit of your ability, you must regularly go past your limits. If you want to bring your whole self to that job, you must push limits in every aspect of your life.
It's not for everyone, but it's the reason why Musk is so successful. He goes right up to the line, and then tries to step just a tiny bit over. Sometimes he ends up flagrantly in the danger zone, but just as often he finds out the line was much further out than anyone suspected.
You can do the same thing socially, by letting crazy people randomly test boundaries, and then using a social network to filter best practices down to you. That way you get the benefit of random testing, without risking any of your personal health or reputation. But that takes decades, whereas Elon's strategy gives immediate feedback.
He has so much privilege that he can be quite risky without actually "betting the farm" so to speak. If he was a little less mentally healthy, a little less white, a little less male, a little less rich parents, a little less educated, etc he'd probably have flamed out with this strategy. Having that intersection of privilege gives him a nice safety net when his experiments blow up. There's a whole other layer of support beyond the business fundamentals.
