I agree with you. Beliefs, grit, talent, skill are all factors in success. But we run into huge issues of post rationalization, survivorship bias, and the human tendency to attribute success to our actions and failures to circumstances (which incidentally is a practice that reduces depression). Uwe Boll's grit created a bunch of awful movies and 3 failed kickstarters - he's much more successful at owning a restaurant! The challenging question is where to focus your efforts. Listening to survivors to the detriment of understanding your current situation and needs can be a trap.
