Write down the most important things you have to do tomorrow. Now, number them in the order of their true importance. The first thing tomorrow morning, start working on an item Number 1, and stay with it until completed. Then take item Number 2 the same way. Then Number 3, and so on. Don't worry if you don't complete everything on the schedule. At least you will have completed the most important projects before getting to the less important ones.
