We simply must get it through our heads that holding a low opinion of ourselves is not a virtue, but a vice.

Your automatic guidance system cannot guide you when you're stalled, “standing still”.

Study the situation thoroughly, go over in your imagination the various courses of action possible to you and the consequences which can and may follow from each course. Pick out the course which gives the most promise and go ahead.

We are built to conquer environment, solve problems, achieve goals, and we find no real satisfaction or happiness in life without obstacles to conquer and goals to achieve.

We must have courage to bet on our ideas, to take the calculated risk, and to act. Everyday living requires courage if life is to be effective and bring happiness.

You may live in an imperfect world but the frontiers are not closed and the doors are not all shut.

Self-improvement is the name of the game, and your primary objective is to strengthen yourself, not to destroy an opponent.
