I have discovered that when what you start goes unfinished it can drain your energy without you even realizing it. William James said, “There is nothing so fatiguing as an uncompleted task.” And the Internet has made the problem even worse, because now you get more “messages” in one day than you used to get in a month. When you don't focus on something, you simply don't finish it. So you end up frustrated, feeling like “nothing is getting done”. If you don't take control of your time, your time will take control of you. You will find that people and seeming urgent situations will eat up all your time and you will have little or no time at all to finish your own business.
