Step by step it "digs itself in" until it paralyzes one's reasoning faculty, destroys self-confidence, and initiative. Worry is a form of sustained fear caused by indecision; therefore it is a state of mind that can be controlled. An unsettled mind is helpless. Indecision makes an unsettled mind.

We do not worry over conditions, once we have reached a decision to follow a definite line of action.
