When you decide that YOU will control how you manage your email, and not the reverse, you’ll find time that you didn’t know you had. Newly flashing email messages can interrupt you all day long if you let them. So don’t let them. The default setting on most email programs is for your messages to “ding” the millisecond they show up on your server. You can, and should change these settings and turn them off.
Interruptions disturb your productive work, and it takes precious time to get back to exactly where you were on that specific task. Grab your email messages when YOU decide to, not when they decide to show up. Every interuption takes the average person an average of 4 minutes to recover. So every interruption you avoid will find you 4 minutes.
