Wikiquote:Quote of the day/April 2, 2011

My success and my misfortunes, the bright and the dark days I have gone through, everything has proved to me that in this world, either physical or moral, good comes out of evil just as well as evil comes out of good. My errors will point to thinking men the various roads, and will teach them the great art of treading on the brink of the precipice without falling into it. It is only necessary to have courage, for strength without self-confidence is useless. ~ Giacomo Casanova ~
