A man can refrain from wanting what he has not and cheerfully make the best of a bird in the hand.
Seneca the YoungerTrue friends are the whole world to one another; and he that is a friend to himself is also a friend to mankind. Even in my studies the greatest delight I take is of imparting it to others; for there is no relish to me in the possessing of anything without a partner.
Seneca the Younger
