"The secret of my incredible energy and efficiency in getting work done is a simple one," [Algonquin Round Table member Robert] Benchley wrote. "The psychological principle is this: anyone can do any amount of work, provided it isn't the work he is supposed to be doing at that moment."
He explained further (tongue in cheek): If you have several things you want to get done, just place them on a To-Do list immediately following the number one thing you are supposed to get done but don't really want to do. Soon, the several things will be accomplished.
Can I get a witness?
