Not speaking from personal experience, of course but it occurs to me that all that is required for ‘success’ is that one’s natural proclivities be aligned with one’s natural talents. Well, that and a whole lot of luck. 😉
I was raised thinking that moral and ethical standards are universals that apply equally to everyone. And these values aren't easily compatible with the kind of religion that posits a Creator. To my way of thinking, an omnipotent being who sets up a universe in which thinking beings proliferate, grow old, and die (usually in agony, alone, and in fear) is a cosmic sadist.
