"Happiness is understanding that friendship is more precious than mere things, more precious than getting your own way, more precious than being in situations where true principles are not at stake."
"The secret of happiness is the determination to be happy always, rather than wait for outer circumstances to make one happy."
"Happiness is an attitude of mind, born of the simple determination to be happy under all outward circumstances."
"Happiness is not a brilliant climax to years of grim struggle and anxiety. It is a long succession of little decisions simply to be happy in the moment."
