Gustav Mahler

de bene esse: literally, of well-being, morally acceptable but subject to future validation or exception

Gustav Mahler was born on this day! After rehearsing his Fifth Symphony, Mahler wrote to his wife, "I see it is in for a peck of troubles!...Oh, that I might give my symphonies their first performance fifty years after my death!" http://bit.ly/1aKvO2K
