Personally, I believe the findings of this research to be true. This is not only because I encounter this often, but my peers do, as well. Numerous projects from any subject generally result in my peers, and potentially myself too, we react either upset about it, or we want to give up at some point, because it can get difficult, especially for last minute project producing. I have spent some nights, especially sophomore and seldom junior year of high school, where I stayed up late to finish a project, and when I mean late, I mean like past midnight, still working on something and feeling miserable and tired continuing the work. My best advice is to try your very hardest to finish something early, so you can then work on another assignment before it gets too busy and so the homework won't build up.
I am sorry you feel that Joe. I agree that getting things done early is the best way to handle research projects. I personally got all of my papers Junior year done two weeks before they were due.
