You are as wealthy as you are certain.

When you let someone change your mind, you let them rob you of your certainty.

You cannot be certain while you are unwilling.

You cannot fail when you are certain.

Be certain independent of facts, when you doubt yourself, you cannot be, you cannot do and you cannot have.

When you go away from certainty, you bring about your failure.

The prerequisite to failure is to stop being certain.

Certainty is the clear absence of right and wrong.

Insanity is total uncertainty.
