"I only do it for between two and five minutes a day, usually right when I get to work while the computer is firing up. Obviously, I have a job to do so I don't spend a lot of time doing it. Plus, there's something about doing it this way that forces me to be patient, something I could always use more practice with. Since I'm doing about five minutes, I'm lucky if I get a section done about the size of my fist each day. It really depends on the specific work.
