Success always necessitates a degree of ruthlessness. Given the choice of friendship or success, I'd probably choose success.

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

True friendship is like sound health the value of it is seldom known until it is lost.

That friendship will not continue to the end which is begun for an end.

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

A true friend is one who overlooks your failures and tolerates your success!

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

Friendship is the shadow of the evening, which increases with the setting sun of life.

Wishing to be friends is quick work, but friendship is a slow ripening fruit.

Never contract friendship with a man that is not better than thyself.
