Mark Twain once said that if you eat the biggest, most important task first thing in the morning, you can get it done and out of the way. This "frog" is the task you are most likely to procrastinate on but completing it can have the greatest positive impact. The first rule of "frog eating" is to complete the ugliest task first if you have two difficult tasks. The second rule is not to delay starting the unpleasant task, but to get it done quickly.
