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

Peace, commerce and honest friendship with all nations entangling alliances with none.

Friendship, like the immortality of the soul, is too good to be believed.

Since there is nothing so well worth having as friends, never lose a chance to make them.

Friendship is always a sweet responsibility, never an opportunity.

Instead of loving your enemies - treat your friends a little better.

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

Caring for but never trying to own may be a further way to define friendship.

I don't need a friend who changes when I change and who nods when I nod my shadow does that much better.

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