Principles man, exactly. It's worse for me to know I could have done the right thing and did not than knowing someone else knew I did not. Personal integrity.
Good luck with the pushups man. It's funny you know, I only just finished doing 786 one-armed pushups right before I read your comment; a good warm up before I start my work out. Now, I better get moving and start bench pressing that 350kg I've just racked up before putting 73 abs images on Instatwit.
