"It is not the critic who counts...The credit belongs to the man who is actually in the arena, whose face is marred by dust and sweat and blood; who strives valiantly; who errs, and comes short again and again, because there is no effort without error and shortcoming." -Theodore Roosevelt
Translation: Quit yapping and jawing about something, get off your lazy bum and do it. Who cares if you f*ck it all up? You can't become great if you never even start. So go to it.
