The main source of good discipline is growing up in a loving family, being loved and learning to love in return.

A human being is happiest and most successful when dedicated to a cause outside his own individual, selfish satisfaction.

The loving person makes other people feel good, and he is usually a happy person himself. He is able to form strong, long-lasting friendships.

Having a good time together is the essence of lovingness and the best means of increasing it.

Boys and girls need chances to be around their father, to be enjoyed by him and if possible to do things with him. Better to play fifteen minutes enjoyably and then say, 'Now I'm going to read my paper' than to spend all day at the zoo crossly.

Happiness is mostly a by-product of doing what makes us feel fulfilled.

Humans can be the most affectionate and altruistic of creatures, yet they're potentially more vicious than any other. They are the only ones who can be persuaded to hate millions of their own kind whom they have never seen and to kill as many as they can lay their hands on in the name of their tribe or their God.
