This is another way of saying that if you have two important tasks before you, start with the biggest, hardest, and most important task first. Discipline yourself to begin immediately and then to persist until the task is complete before you go on to something else. You must resist the temptation to start with the easier task. You must also continually remind yourself that one of the most important decisions you make each day is your choice of what you will do immediately and what you will do later, or postpone indefinitely.
