There, I said it. Need to concentrate – get something important done? Turn off all that outside stimulation – all of it! Everything that’s out there reminding you that there is a world outside. Let’s make a list: your phone (home, office and cell), your email notifier (ding!), the radio (real thing or internet), no text notifications. Anything else? If you don’t need it turn off your computer as well. It will keep you from being tempted to send some time surfing.
Will you miss anything? No. Will you get your project done more quickly, more efficiently? Yes. Don’t worry. It will all be waiting for you when your work is done.
