Cultivate friends who pray for you, not prey upon you. Fall sick and you will know who is your friend and who is not. Friends slowly won are long held. Man's best friend is his dog. If you want a friend, you will have to be one.
Old friends are best.
One does not make friends, one recognizes them. Never drop the friends you make on the way up. You may need them on the way down. Never trust a friend who deserts you in a pinch. Speak well of your friends, of your enemies say nothing.
