After some trial and error I started to realize that shorter stints of work spread over the entire day lead to much greater results. I now start work around 11AM, deal with emails/first morning problems, take a lunch break at noon, then put in around four hours of solid work in the afternoon. I relax throughout the evening and then go back to work for the last 3-4 hours before bed. I am now able to put in a far more productive number of hours and my output has increased significantly.
With that, I have to disagree with a lot of the points in the article. Home is not the office. You need to change your work habits to fit into your new place of work, not try to make your home fit your work habits. In my experience, trying to move your office into your house is bound to fail. Change the way your work, however, and your potential for greatness exceeds that of working in the office.
