> So I guess not reading books might come from having a closed mind which could be solved by reading.

Reading does not necessarily solve a closed mind or actually "improve" a person. I am not a believer, or fan, of the mindset that reading is "good" for you, or always improving somewhat or better than all other hobbies at something.

And mandatory perspective I read lots and always have, own way too many books, but trust me a lot of books I read did not "improve me" necessarily and that is not why I read or I look for new things to think, or relaxation it can be on many things. Somebody iliterate can be observant and tolerant and intelligent.
