We all know the feeling of being overwhelmed, of being beset by distractions. The problem is – too many things are clamoring for your attention. People are trying to reach you, by phone, email, text, Twitter, IM, or old-fashioned yelling up the stairs. There are the interesting subjects you want to learn more about, on the TV or the internet or the newspaper. Noises in the background occasionally catch your ear, from the TV or radio. Your kids all talk at the same time. Colleagues interrupt. You need to update, check in, post, or ping. Ads jump at you from the most unlikely places. Devices buzz, ring, chirp, and vibrate. It’s enough to drive you crazy. You lose your train of thought, you forget what you’re doing, you have trouble re-engaging in a task, you feel besieged.
