Per Scott Adams' "Passion is Bullshit", what really helps with motivation is to succeed already. If you have good luck and your initial efforts pay off, you'll probably want to build on that. If you have bad luck and it all collapses, you'll probably want to stop. The lesson there is, I don't actually know. Try sometimes maybe but don't overdo it?
Yes, entirely unaware. I had a hunch it would be that he said or did some terrible thing, but I don't suppose it diminishes the value of this concept about motivation, does it?
