If you truly want to be successful, start thinking of yourself as successful.
The only thing that stands between you and what you want from life, is simply the will to try it and the faith to believe that it is possible. There is nothing on earth that you can't have, once you mentally accept the fact that you can have it.
The feeling must come first. If you actually feel successful, if you have a deep inner conviction that you'll always have all that you need, it will be so.
Whatever your mind can conceive and believe in, your mind can help you achieve.
