The problem I see is in the question itself. 1. "reading a lot", don't read for the sake of reading or learning for the sake of learning. Choose what you find interesting and read that. 2. "feeling of not memorizing". Read slower, know what it is that you're learning. Try to internalize every little 'oh' and 'ah' moment. Read critically thinking along the edges, wondering if it does or doesn't apply to similar cases. Think them through and decide if you feel it should or shouldn't apply. Learning is not about remembering. It should be about connecting new information to information you already know. Take the time to find and make those connections as you're reading. It's not likely that this will happen on its own--perhaps if you read the same material before and after a related experience, but that can't be planned.
