“Purpose gives rise to discipline, restraint, and self-control, which are crucial, fundamental tools for success in the journey of life.”

“For God did not give us a spirit of timidity, but of power and of love and of calm and well balanced mind and discipline and self-control.”

“Without self-discipline, success is impossible, period.”

“The essence of successful discipline is not technique; rather, it is self-confidence.”

“Self-control is a key factor in achieving success. We can't control everything in life, but we can definitely control ourselves.”

“There must be only three supreme values which govern a person's life: Reason, Purpose, and Self-esteem. Reason, as his only tool of knowledge--Purpose, as his choice of the happiness which that tool must proceed to achieve--Self-esteem, as his inviolate certainty that his mind is competent to think and his person is worthy of happiness, which means: is worthy of living. These three values imply and require all of man's virtues, and all his virtues pertain to the relation of existence and consciousness: rationality, independence, integrity, honesty, justice, productiveness, pride.”
