Improve thyself

I go to the gym 3x per week too. I see a personal trainer once a week, which kind of keeps me waking up at decent times during the week (otherwise I have a bad habit of sleeping in every day til the afternoon)

Used to surf, no better sport imo. Now I'm getting fat because I've become lazy and/or lack of time.

Why is it that so many of us, when left without someone else to dictate a structure to our day, will sleep until the afternoon each day. Surely the opposite should be true and we should naturally take our daily cycle from the sun.
