Some people learn by doing, or learn by example, and the faster they can get into doing an example, the faster they will learn.

I am one of those people, and I can't count how many textbooks I own, of which I've read the first few chapters, and lost interest because I wasn't doing anything, only reading.

When I can instead start doing something, as GP emphasized, I can learn the applicable concepts as they're applied, which works well for me. AI helps me do that, because it is like a textbook that follows along with me, rather than asking me to follow it. Also I ask a lot of questions.
