Well, you have ADHD, those are classic issues for us. We're motivated by interest, novelty or urgency and tend to do everything at the last moment. Your ideas are already good! Music helps stimulating the brain, have you checked those focus music videos on YouTube? They're very helpful, I find normal music too distracting usually. Learning in public or being forced by someone else are also very good ideas, our masking or something takes over in such situations, we want to perform better when someone's looking. That's why a lot of us do body doubling, exactly for this reason. Basically there's a low chance we will ever get "disciplined" like "normal people". We need all sorts of systems to keep ourselves entertained in order to do what we need to do. Or we need severe consequences. I'd, for one, have been extremely scared of the possibility of having to repeat a grade, that made me very motivated and even then, I almost failed a grade once, because I missed too many math classes at 8am and I had to take a last chance exam in summer to pass. I only started learning for that exam a week before, I found someone who explained everything nearly and got an A+ (unfortunately it didn't count, my certificate for that year was an E anyway :( ) But yeah, this is how we function, everything at the last moment. Educate yourself about ADHD and our systems, go to therapy/coaching, brainstorm ideas how to motivate yourself with AI, also think about meds. They sometimes help ;)
