Set a timer for 48 minutes. Close out all distractions and work continuously for 48 minutes. When the timer goes off, get up and stretch, get coffee, use the restroom etc, in the following 12 minutes. Repeat as necessary.

Don reports that this technique repeated four times a day allowed him to write a 200 page book in just two weeks. The ability to focus on one task for 48 minutes straight was the key. I have been testing Don’s idea and I have to say it works well for me. This eliminates the distractions that have a way of derailing even the best laid plans. Taking a short 12 minute break once an hour is refreshing but not enough to get you off track.
