>> I wrote at home, in the mornings, in three separate, highly focused 90 minute sessions. By the time I finished the last one, I was usually exhausted — physically, mentally and emotionally. I ate lunch and then took a 20 to 30 minute nap on a Barcalounger chair, which I bought just for that purpose. >> When I awoke, I felt incredibly rejuvenated. Where I might otherwise have dragged myself through the afternoon, I was able to focus effectively on work other than writing until 7 pm or so, without feeling fatigued. I actually work on a very similar system except it is 2 3x45 minute sessions instead of 3 90-minute sessions. Like the author though, I find I can't do anymore programming after 4.5 hours of productive work but after taking a nap , I have lots of energy to do other activities that interest me.
