I love reading, I could devour a good novel in a couple of days when I was younger. However I find it harder to read nowadays. I tell myself it's because I have so much going on, and little time to read, but I also think I find my attention wanders far more, and I think as you grow older you do get busier with work and responsibility, and you have less time for all the hobbies that you used to pursue.
I have been making time for more reading recently though, as I keep having it pushed on me that the more you read, the better your writing will be.

So I've been trying to focus on reading a little every night, making a list to work through and concentrating on giving a little time to reading.
I mark my bible as well, but I never make notes in books. I use a bookmark to keep my page, and that's it.
