There are no real barriers to your success. You must simply overcome any doubts you have about your ability. Your self image prescribes the limits for your accomplishments. It prescribes the area of what is possible for you.
Don't be afraid of living. If you believe that life is worth living you will create that fact around you. If you see yourself as prosperous, you will be. If you see yourself as broke, that's exactly what you will be.
You will never succeed until you believe you can succeed.
