Impotent hatred is the most horrible of all emotions; one should hate nobody whom one cannot destroy.
Be above it! Make the world serve your purpose, but do not serve it.
If you are convinced of a matter, you must take sides or you don't deserve to succeed.
Men are joined by conviction, sundered by opinion.
Man errs, till he has ceased to strive.
If you've never eaten while crying you don t know what life tastes like.
