Be happy with what you have and are, be generous with both, and you won't have to hunt for happiness. - William E. Gladstone
Our greatest happiness does not depend on the condition of life in which chance has placed us, but is always the result of a good conscience, good health, occupation, and freedom in all just pursuits. - Thomas Jefferson
Achievement of your happiness is the only moral purpose of your life, and that happiness, not pain or mindless self-indulgence, is the proof of your moral integrity, since it is the proof and the result of your loyalty to the achievement of your values. - Ayn Rand
