One can do without people but one has need of a friend.

Chinese Proverb

The key is to keep company only with people who uplift you, whose presence calls forth your best.

Epictetus

Above all, don't lie to yourself. The man who lies to himself and listens to his own lie comes to a point that he cannot distinguish the truth within him, or around him, and so loses all respect for himself and for others. And having no respect he ceases to love.

Fyodor Dostoyevsky

Every lie is two lies, the lie we tell others and the lie we tell ourselves to justify it.

Robert Brault

If we are to judge of love by its consequences, it more nearly resembles hatred than friendship.

François de La Rochefoucauld

The only reason why we ask other people how their weekend was is so we can tell them about our own weekend.

Chuck Palahniuk
