I've found the best way to learn something is to be willing to make the attempt despite limited confidence. This sort of fearlessness makes a person seem like an idiot, but as long as you keep learning from mistakes you keep getting better.

The people who spend all their time trying to not do something stupid, end up just learning how to not look stupid and how to do it the way the person before did.

Does Elon Musk look like an idiot on Twitter? Totally! Is he learning? It's a pretty good bet. He's a human being who is willing to take the risk of looking stupid. It's a luxury afforded to most billionaires.

Based on his recent Twitter activity, no, I don't think he does.
