Creating to-do lists can become a compulsive habit as it helps us feel organised. The problem is, just because we put it on a list doesn't mean we're going to do it. We often get stopped up during the day by tasks that suck away our time. To get rid of these productivity-killing tasks, put them on a "to stop" list.
This idea comes from healthy living blog Zen Habits. They suggest creating a list of all the things that are wasting your time and draining your energy. Rather than concentrating on what you have to get done, concentrating on knocking a thing or two off of your "to stop" list. The idea is that when you eliminate these problem tasks, you won't necessarily need your to-do lists because you'll have the time and energy to remember them and get them done.
