When friends succeed

Whenever a friend succeeds, a little something inside me dies. Gore Vidal

Failure is not the only penalty for sloth - there is also the success of ones friends. Anon.

Failure, so despicable in others, in oneself the only dignified thing. Claude Cockburn

And everyone knows:

We all of us have the fortitude to bear a friend's misfortune. La Rochefoucauld
