It is possibly confirmation bias. But it is one I embrace: it lets me continue to dream, take risks and help people out. A little self-delusion is a small price to pay for all that.
That made me smile :) That being said, I agree with your sentiment. And in the end, even if it doesn't work out, you never waste time by doing the right thing. I'd rather end up broke and do "the right thing" than to make money with a business I don't believe is making the world a better place. Moreover it seems doing the right thing is more likely to make you money which is kind of nice :)
And, yes, I am aware that I am very lucky.
