Self-discipline is the ability to make yourself do what you should do, when you should do it, whether you feel like it or not.
Elbert HubbardThe great man is not so great as folks think, and the dull man is not quite so stupid as he seems. The difference in our estimates of men lies in the fact that one individual is able to get his goods into the show-window, and the other is not aware that he has any show-window or any goods.
