A man's growth is seen in the successive choirs of his friends.

A true friend is someone who is there for you when he'd rather be anywhere else.

Am I not destroying my enemies when I make friends of them?

I value the friend who for me finds time on his calendar, but I cherish the friend who for me does not consult his calendar.

The sincere friends of this world are as ship lights in the stormiest of nights.

One of the most beautiful qualities of true friendship is to understand and to be understood.

Friendship is unnecessary, like philosophy, like art... It has no survival value rather it is one of those things that give value to survival.

Be true to your work, your word, and your friend.

As iron sharpens iron, so a friend sharpens a friend.

The best time to make friends is before you need them.
