The key to becoming a stock-market billionaire is taking big risks. But that does not mean it works for everybody it actually works for very few the lucky few.

Same thing probably happens with startups. You don't start a startup unless you have Blind Faith (btw. great album). But only a few of the startups make it big. When we see the ones that made it we may see that none of them would exist unless their founders had had blind faith. So (more or less) Blind Faith seems to be a prerequisite for success. But it is not a guarantee, far from it.
