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

Friendship is certainly the finest balm for the pangs of disappointed love.

There are no rules for friendship. It must be left to itself. We cannot force it any more than love.

If you have one true friend you have more than your share.

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

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

Friendship is the source of the greatest pleasures, and without friends even the most agreeable pursuits become tedious.

Let there be no purpose in friendship save the deepening of the spirit.

True friendship can afford true knowledge. It does not depend on darkness and ignorance.

In friendship as well as love, ignorance very often contributes more to our happiness than knowledge.
