Don't be afraid of what life has to offer you. If you believe that life is worth living, your belief will help create the fact.
The barrier between you and success is not something that exists in the real world. It's simply composed of doubts about your ability. Your only limits to your realization of tomorrow will be your doubts of today.
If you want to be successful, start thinking of yourself as being successful.
What you believe yourself to be, you are. Success is a state of mind.
