Epicurus

If thou wilt make a man happy, add not unto his riches but take away from his desires.

It is folly for a man to pray to the gods for that which he has the power to obtain by himself.

Not what we have But what we enjoy, constitutes our abundance.

Death does not concern us, because as long as we exist, death is not here. And when it does come, we no longer exist.

Do not spoil what you have by desiring what you have not; remember that what you now have was once among the things you only hoped for.
