I'm in the same boat as you chief. I'm independent, working part time, go to school full time, I commute to and from university (23 miles), work and home (5 miles).... (405 freeway suck big time!!!)
I got bills and all that mumbo jumbo that every adult individual have to deal with but when midterms and exams is lurking around the corner, stressing out is the first thing i do.
Then my girlfriend told me to make a schedule the night before and try to stick to it specially during the weekends. I got to say that it really works!
First thing first, masturbation really works especially in the morning when you just woke up. It gets your blood pumping and it somewhat distracts you from whatever you're thinking. After that, just go ahead and follow your schedule. It should be an hour after hour type of schedule and factor into it your meals or break hours no matter how long it is.
But to be honest with you, next week is my midterms. I am taking three classes and I have probably read 10 pages total on all the assigned readings... I'm the master procrastinator! I'm also a master-(de)-bater!
To add to the dilemma... I have band practices on firdays plus there's the de la hoya - mayweather fight on saturday which falls on cinco de mayo... dilemmas... dilemmas...
In my case, I guess a schedule still works for me although sometimes (more like often) I completely brush it aside....
