Never have a companion that casts you in the shade.

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

Be courteous to all, but intimate with few, and let those few be well tried before you give them your confidence.

Friendship improves happiness and abates misery, by the doubling of our joy and the dividing of our grief.

Never make friends with people who are above or below you in status. Such friendships will never give you any happiness.

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

The language of friendship is not words but meanings

Peace and friendship with all mankind is our wisest policy, and I wish we may be permitted to pursue it.

Friendship is always a sweet responsibility, never an opportunity.

No person is your friend who demands your silence, or denies your right to grow.
