Kostya, that sounds more like an extended version of the "scrubbing the toilet instead of studying for the exam"-syndrome. It's a more energetic version of procrastination, where you clean the house and bake cookies rather than sit on your ass and play videogames. But it's still procrastination.
ooh_shesus said a good thing about accepting yourself as a procrastinator. The trick is to find a balance between embracing your procrastination and still maintain enough "shame" to actually get things done.
I'm a procrastinator too. The only times I get things done are either at the last minute or as soon as I get the assignment. The latter happens very seldom though.
The few times I've actually been able to do the whole process with brainstorming and sorting and structuring and first draft and critical review and second draft shebang kind of thing it has been incredibly awarding and I've told myself I must do this again. But you know how it goes... Still, I usually am able to enjoy myself when I finally sit down and do the assignment. If you find no joy in your work at all, that's when you really should start worrying.
