Yiddish Rabbi
Throw a lucky man into the sea, and he will come up with a fish in his mouth.
Be master of your will and slave to your conscience.
Who looks for a faultless friend will have none.
By your friends I gauge your wealth; by your enemies, your greatness.
Old age, to the unlearned, is winter; to the learned, it is harvest time.
Bad habits are easier to abandon today than tomorrow.
