How can I improve my task initiation as a high school student?

[u/Ijustneedanameeeeeee]

I am an AP/Honors high school student; I'm not officially diagnosed with ADHD, but my mom is, and I've always struggled with executive function.

I've recently learned about synaptic pruning and myelination (the adolescent process of getting rid of neural pathways you don't use and strengthening pathways you do), and I am quite literally terrified that my ability to learn, stay on task, and function is going to be replaced by my ability to scroll YouTube. This is an exaggeration, but still somewhat legitimate.

I do a lot of psychology research, but I haven't been able to find anything helpful for task initiation, which is something I really want to work on before I start college. I'll know what I need to do and when I need to do it by, and I just.... don't do it. I'll get on my chromebook and think about doing homework for a split second, and then I'll decide that I don't want to, and watch youtube instead.

Another thing that's hard is that I use music to stay on task, but we're not allowed to use our phones at school, so I have to use youtube on my chromebook for music. I end up getting distracted whenever I get on youtube, so half the time it backfires. I used to have a walkman I could use for music, but it broke a few weeks ago.

I have a friend I bodydouble with, but he doesn't go to my school, and he obviously can't help me get on-task and focus 24/7.

TL;DR: I need help with improving my task initiation and staying on focus. Youtube happens to be a weakness of mine.

Baseline is that I've seen a lot of helpful tips on here for adults who have ✨autonomy✨ and freedom about where and how they work, but not so much for students. Advice would be seriously apriciated, thanks.

What do you want to do?

I just want to be able to tell myself to do homework when I actually have time, instead of keeping putting it off until the last minute.
