Risk tolerance is a component of character. Musk has put his entire fortune on the line more than once, and more than once was a whisker from bankruptcy.
I'm far less of a risk taker than he is, and have consequently not made big scores like Musk.
I'm going to reserve judgement on that because the media lens is pretty distorting. He's not afraid to stand up to bullies, and I've seen that interpreted as assholishness.
Steve Jobs also had a reputation as an asshole. A couple of my friends had encounters with him, and I asked is he really an asshole? Both confidently said yes. !!
