I had similar issues, I started pre-crastinating.

By that I mean artificial deadlines that I set for myself (I need to get this assignment done 1-3 days before it's due so I have time to take a quick glance at it right before I hand it in). These were hard deadlines that I pulled all-nighters for. I didn't actually change any habits to become a model student, I just changed the order in which I did unhealthy things.

This eventually lead to me being able to get into the habit of breaking up homework into doing x amount of problems per night, like the top students in my class usually did.

For final projects with less discrete milestones than answering some problems, I still found it difficult and never got used to that. I still pulled all-nighters but aimed my fake due date to a week before, and made it a bit softer so it was okay to sleep if I was more than half done.

I raised my grades from barely passing to decent student. Never got to A+ student but I think was getting there.

I used to never stick to to-do lists, and I still don't like them. I don't like the obligation and feeling like a failure when it's left not completed. I have to do stuff as it comes to me, or know I'm setting out a block of time to do it later that day.

Lifelong procrastinator here. Never been diagnosed but I definitely suspect ADHD. I do take something for anxiety, which hasn't fixed my procrastination, but has helped me not feel so shitty about it all the time.

Things that help me the most: include other people! I'm much happier to work with others than by myself. Find ways to include friends in activities you need to do. The other thing is to fill up your schedule a bit more with commitments that you can't/won't blow off. This tends to keep you "in motion" which you can leverage to get other things done too. Good luck :)

I procrastinated pretty heavily even into graduate school. I had two years to write my thesis and I ended up doing most of in the last few months of the program (it actually came out pretty well). Honestly it wasn't until I was in an upper management position, and in charge of project management, that I really got over it because of how many people were reliant on me. It was always getting started on something that was the hard part for me, once I get started on something I have zero issue focusing on it until I am done.

For me, it was a matter of just coming to know myself and be realistic. Todo lists or reminders never worked, because they just made me feel like I accomplished something by making the list, when I was really still just putting it off. Most of the time now, if there is something I know that needs to be done, I do it immediately. Not just in work; if I finish cooking I wash all the dishes immediately. Notice my desk is getting messy? Immediately pull out the cleaning supplies.

People now think I am super proactive because we always finish projects first regionally. I suppose I technically am, but that is only because I know it will never get done if it isn't done immediately. I might try to convince myself otherwise, but I just know the type of person I am. It also feels nice to finish things early and then have guilt-free free time afterwards.

I am not saying the same methodology will work for you, but just be aware of yourself and your habits. If you tell yourself you will do X task tomorrow/after lunch/after a break, are you really being honest with yourself? For some people, the answer is yes they will absolutely be able to do that.

Does this describe your situation?

I used to procrastinate but now I don’t. I don’t know if my experience would help since I was just playing games all class, and now have no homework because I do all my work in class.

Meditation always helps me clear my mind and summon the executive function necessary to do househols chores.

Amphetamines aka Adderall really helps. Methamphetamines aka Desoxyn is even better. Just be very very careful with it.
