Most successful people are failures at hundreds if not thousands of things before they find success. Stock traders must incorporate being wrong regularly into their plans. Most new ideas will probably fail. It is the tenacity to keep trying that differentiates successful people. Train yourself to recognize potentially successfully things and plan on being in a position to capitalize on them. You make your own luck.
There is a novel by Ayn Rand called the Fountainhead. It is criticized heavily, and rightly so, for some poor choices the novelist used, but its central story is about the architect Howard Roark (who was loosely based on Frank Lloyd Wright) who was publicly disparaged as possibly being insane for the first twenty years of his career. To read about his life changing and how public view changed to the point that he became the inspiration for most modern architecture (maybe not quite true, but close) WITHOUT CHANGING A SINGLE ONE OF HIS VALUES, is really empowering for me. He never ever comprimised one bit. He did not cheat. He dedicated himself to his work and making it the best it could be.
