procrastination

It's a mid-term week. I had 2 exams and one more this week. I hate myself that I didn't start studying few weeks earlier. I always regret when I have to cram the night before the exam. With lack of sleep, my exams cannot be my best work. I am in bad condition right now. Of course, it is a mid term week and I didn't get enough sleep. I always do that when it comes to paper. I am supposed to consider and choose a theme carefully and research the data as soon as I can, so that my paper would be a good one. But, I procrastinate all the time, and choose a theme randomly. After I got low grade on my paper I told myself that not to do this again, but on the next assignment, it happens again. I believe it is not only me who go through a repetition of procrastinating and regretting.
