I've read that most procrastination problems come from anxiety or perfectionism (fear of not being able to do X perfectly, low self-esteem / fear of being ridiculed for your work etc)
I have adhd and I would suggest you get that checked out because it sounds similar to how I experience it. Also search for hyperfocus online, it is what happens if people with ADHD get interested in something! As I said in another post, I get immensely interested in a new hobby like e.g. playing DND or learning how to play the guitar for one, two, maybe three weeks and after that - nada. Except "high dopamine" stuff like video games.
I have ADHD and while giving up easily is an indication for ADHD I have also a washing list of other symptoms, e.g. switching to a new hobby every other week, having sudden urges to google random things because my brain thinks it is of utmost importance to know about it RIGHT NOW, inability to maintain concentration if the thing I have to do doesn't interest me - but hyperfocusing on things for days on end if they interest me etc etc
ADHD is much more centered around concentration than just giving up easily, I guess.
And I'm sure, 100% sure, that I'm not the only one with that problem...
