Like most things, it's not an extreme of one or the other. Once you stop reading and start doing, it's not like you can never go back to reading. If you dive into doing right away, that doesn't mean you can't go back and read. Studying, doing, reviewing is a good feedback loop. You study what you're going to learn in small chunks, spend some time grinding it out and working on it the best you can, then stepping back and reviewing your progress or lack thereof. Then back to reading, either reviewing what you read before, or moving onto the next chunk if you've mastered the previous one.
