Nothing is so fatiguing as the eternal hanging on of an uncompleted task.
—William James (1903, by Notman Studios; Public Domain)

On the flipside, few things in life are as energizing as the methodical completion of well-thought-out tasks; actions designed to move you closer to your goals. Don’t allow this process to be arbitrary. Know what must be completed going into each day and have a specific tool—be it pen and paper or an effective time management app—for recording the completion of these tasks. As a bonus, odds are strong that you will sleep more soundly, content with what you have just accomplished.
—Mike Hazell
