While it feels easy enough to put one task on hold to start another, studies like this are a reminder that we find it very difficult to let go of unfinished challenges. They continue to draw on our mental resources even after we think we’ve switched focus. What’s more, attempting to ignore this mental tug drains us even further. If you can, it’s best to find a good stopping point on a project—one that frees your mind from nagging questions—before moving on to another task. That way, you’ll find it easier to achieve mental closure and apply all your energy to the next challenge.
