i've been mainly using chatgpt to learn. i can drill it endlessly for concept i dont understand. Previously i was forced to move on with holes in understanding.
also the new ui that is more visual is making a huge difference. only think i dont like is that i take a lot of detours but chat is linear instead of a tree.
What worked for me was building a system that lets me think consistently everyday. And by system, I mean sitting in a library with paper books and if really necessary, with my existing laptop.
