The task ahead of us is never as great as the power behind us.

Vigor is contagious, and whatever makes us either think or feel strongly adds to our power and enlarges our field of action

That which we persist in doing becomes easier for us to do; not that the nature of the thing itself is changed, but that our power to do is increased

Each one of us has the power to make others feel better or worse. Making others feel better is much more fun than making others feel worse. Making others feel better generally makes us feel better.

There is no knowledge that is not power.
