Look, I think everyone procrastinates in one form or another. The key is to know when it's time to procrastinate on the procrastination (meta, huh?). In other words, you have to delay your procrastination to get the job done. It differs from person to person, so you need to find a way to do that effectively. I'm also guilty of procrastinating pretty frequently, but I've figured out how to manage it such that it doesn't affect my grades and/or work performance too much.

Regarding your comment on ECE, I also found that I enjoyed some courses more than others (I did enjoy most though). For example, I absolutely hated my power systems and power electronics courses. The latter was one of the only courses I got a B+ in, so I didn't do well in it either. As one of the other commenters mentioned, you need to get used to the fact that you won't enjoy everything in your field/job. The trick is to learn how to deal with it and get it over with, or try to work on it with someone who loves the topic you hate.
