There is nothing on this earth more to be prized than true friendship.

Even where friendship is concerned, it takes me a long time to trust people.

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

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

True friendship ought never to conceal what it thinks.

Never explain - your friends do not need it and your enemies will not believe you anyway.

A friend may well be reckoned the masterpiece of nature.

Friendship without self-interest is one of the rare and beautiful things of life.

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

Friendship multiplies the good of life and divides the evil.
