You might have a lot of false starts today -- your concentration isn't terribly strong. After a few minutes of working on or reading one thing, you could become very distracted and start working on something else. In order to avoid wasting your energy, do yourself a favor and get organized! Plan out your day loosely -- you don't have to schedule it down to the minute. Commit to doing one thing at a time and avoid the illusion of productivity that multi-tasking creates.
