Yes. My problem is very similar. Sometimes its because I think I'm stupid, but sometimes I'm almost afraid to start (because I'm worried about failing) or the task just seems too large. Maybe my approach has too many issues that I don't know how to address. Sometimes its just that I don't know where to start.

When I was in college I also had this problem, but then I would realize things were due in a day or two and I'd just figure everything out (often in one all-nighter). I'm finally starting to get over this.
