I have been on this same class FOREVER. I have the same problem you do...it doesn't help that I keep finding other things I'm more interested in.
I think what would have been best (for me at least) is if I had gone to a normal 'brick'n'mortar' school so I could get some structure.
Instead, since I have already spent so much here, I am going to see if I can get someone to 'force' me to work on this at certain times of day...I read somewhere once that if you stick to something for a couple of weeks, it will become habit. Like say a certain time of day be devoted to your schooling and reward yourself somehow for obtaining some small goal...like a piece of chocolate for finishing a chapter or whatever 'floats your boat'. Speaking of, I should probably go try to get a little done now
