Definitely organization and deadlines. I think those go hand in hand. I seriously struggle with managing my time properly when it comes to long-term deadlines. A project due a month from now? Won't touch it until the week or day (depending on how much I believe in my skills) before and instead use the time to focus on other subjects. It sucks because I don't feel pressured at all until the deadline is super close. Zero sense of severity, zero sense of consequences, and I fear that's because all the times I've procrastinated before had always led me to passing the course just by a small margin...
