You will have all the energy you need to get stuff done today, so don't worry about pooping out. You can get a lot achieved if you organize your time and delegate little tasks to other people. There are people who are not only ready, but eager to help you accomplish a few things today, so why not let them? You are more admired than you realize, and you could serve as an important mentor in someone's life. Give them greater responsibilities and they will rise to the occasion.
