There's nothing wrong with procrastination. Why do today what you can leave for tomorrow?
My worst example of procrastination is when I had this long essay for history which was 20% of my final grade. We had to choose a topic and complete it (we had many many months). The essay had required us to do research, add footnotes, compile our bibiography and write a unique answer (as well as choose a unique topic) but I ended up choosing somebody else's last resort topic and I started it on the last two days and I onlly managed to get a D, which is better than what I thought I would get.
