I find reading books quite meditative and I like the initial challenge of maintaining my concentration for the first 10 minutes or so before I can relax and sink into it a bit. I sympathise with everyone else struggling to read as much as an adult though, it was so much easier for me during childhood. Sometimes I feel a bit embarrassed about how little I read now given how advanced I was as a kid. It feels like I've been wasting a skill/hobby that could have provided me with a lot of happiness and growth as an adult.
