power you have, but they help to create new power:
"It Couldn't Be Done"
It may be that you have been deluded by the thought of incompetence. It may be that you have been told so often that you cannot do certain things that you've come to believe you can't. Remember that success or failure is merely a state of mind. Believe you cannot do a thing---and you can't. Know that you can do it---and you will. You must see yourself doing it.
"If you think you are beaten, you are;
If you think you dare not, you don't;
If you'd like to win, but you think you can't,
It's almost a cinch you won't;
If you think you'll lose, you've lost,
For out in the world you'll find
Success begins with a fellow's will---
It's all in the state of mind.
