I stress so much about getting things right that I miss deadlines. It's my biggest problem and it makes me procrastinate - if I can't get something perfect, then I don't want to do it at all. Deadlines are so important and I can't keep missing them just because I am worried about not being perfect.

I'm gonna work on things like:
time management - set myself a certain amount of time to get x amount of work done each day, and then NOT go back to it. Just move on from it. Try not to worry about it.
critique - I really need to stop worrying about getting critique from my tutors. When I finish something (and I'm happy with it), getting critique makes me feel like I have failed. It doesn't matter if the mark sheet says that I passed. I have to learn that my work will always receive critique, no matter how 'perfect' it is.
organisation - I need to keep my work in organised files so it is just easier for me to access my work. Sifting through 50 files for one file is really stressful D:

Anyway, I think I hit the nail on the head for why I procrastinate. Hopefully if anyone else has similar issues, they can relate to all this (:

UPDATE:

Ok so it's been pretty tricky getting the perfectionism thing under control, but last week I managed to get an assignment done on time, and tomorrow I'll be handing in a bunch of things that were overdue and I'm actually happy with how one of the assignments turned out!
