Are you actually able to get all of your work done by 5pm on a consistent basis? I really like the idea you're promoting (and I may well try it myself), but that seems like a stretch for me. Between 2.5-3.5 hours of class a day, lunch, and the time it takes to go from class to another etc, that would really only leave me 2-3 hours for work every day...I honestly don't think that would be enough even if I could focus 100% for the whole time. Is your experience different?
