Don't be afraid of what life has to offer you. Believe that life is worth living and your belief will help create the fact. The barrier between you and success is not something that exists in the real world. It is simply composed of doubts about your ability. Your only limits to your realization of tomorrow will be your doubts of today.
Success is a state of mind.
If you want success, start thinking of yourself as a success. What you believe yourself to be, you are. Perhaps even at an early age, we traded our joy for approval, acceptance, and the illusion of security. But the only real security is in living life from the heart, not hiding out in convention. The good news is that it is never too late to have a happy childhood.
