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

A true friend never gets in your way unless you happen to be going down.

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

Nothing so fortifies a friendship as a belief on the part of one friend that he is superior to the other.

A true friend never gets in your way unless you happen to be going down.

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

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

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

Silences make the real conversations between friends. Not the saying but the never needing to say is what counts.

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