The happiness of your life depends upon the quality of your thoughts; therefore guard accordingly.
It matters not what you are thought to be, but what you are.
Characters do not change. Opinions alter, but characters are only developed.
If you have an hour, will you not improve that hour, instead of idling it away?
As the sculptor devotes himself to wood and stone, I would devote myself to my soul.
He who conquers others is strong;
He who conquers himself is mighty.
Be not afraid of growing slowly; be afraid only of standing still.
Never lose a chance of saying a kind word.
Do not forget small kindnesses and do not remember small faults.
