A kind and compassionate act is often its own reward.

It's been claimed chimpanzees act mainly for their own ends, but in our experiment there was no reward, and they still helped.

It is wrong to expect a reward for your struggles. The reward is the act of struggle itself, not what you win.

Peace is its own reward.

An act carelessly performed, a broken vow, and hesitating obedience to discipline, all this brings no great reward.

It is the amends of a short and troublesome life, that doing good and suffering ill entitles man to a longer and better.
