Lately, I have been writing "Done" lists. Sounds different, right? This is especially good for people who are dealing with time management issues. I write down what I did, check it off, and how long it took to complete the task.
Why does this work? Many of us underestimate the time it actually takes to complete a task. This is the essential cause of the anxiety from looking at an incomplete "to do" list. Not only that, we don't take distractions into account. Write those down too. Are there ways you can eliminate them or minimize them? More than likely. Once you understand how much time you need to get your tasks done it will be easier to make a "to do" list based on your time frame.
But, most of all, allow some flexibility and time for yourself!
