Balance your thoughts with action. — If you spend too much time thinking about a thing, you'll never get it done.

Part IV: On Achievement
The happiness that is derived from excitement is like a brilliant fire — soon it will go out.
Don't get set into one form, adapt it and build your own, and let it grow, be like water.
Faith makes it possible to achieve that which man's mind can conceive and believe.
