I worked the same way until I started doing correspondence courses. With nobody to hassle me, no classes to hand stuff in at, and no peers I had to learn to motivate myself and follow a schedule fast.
I am motivated well by deadlines as well, but its amazing how much easier schoolwork is when you actually choose when to do it. instead of cramming in a sleep deprived state for the night before, you can break it up into easier pieces when you are most alert. Hopefully these newfound skills will carry over when I start university...
Thats an interesting definition of philosophy, but I think philosophy does far more than that.
