Everything has its wonders, even darkness and silence, and I learn, whatever state I may be in, therein to be content.

True happiness... is not attained through self-gratification, but through fidelity to a worthy purpose.

Your success and happiness lies in you. Resolve to keep happy, and your joy and you shall form an invincible host against difficulties.

Many persons have a wrong idea of what constitutes true happiness. It is not attained through self-gratification but through fidelity to a worthy purpose.

No one has a right to consume happiness without producing it.
