Materialistic success can be explained quite simply. Those who succeed focus their attention on success - not on their talent. Remember these words! All of their efforts are focused toward the upward movement rather than the perfection of their artistic ability. Neither do they allow anyone to anything to stand in the way of reaching their goals. This includes wives, families, friends and their children. They are prepared to pay the very high price that success demands.
At the end of the day, all you really have is your own sense of your artistic ability and I've always stuck with that my whole life. I guess there is always a bit of relief that I have and real joy of being able to engage other people who are talented, equally or better than you, and you can work with them.
