If your goal in life is to become fearless, then I believe you're already on the wrong path, because the only truly fearless people I've ever met were straight-up sociopaths and a few exceptionally reckless three-year-olds--and those aren't good role models for anyone. The truth is, you need your fear, for obvious reasons of basic survival. Evolution did well to install a fear reflex within you, because if you didn't have any fear, you would lead a short, crazy, stupid life.
