How can I change what I'm entertained by?

I have this weird feeling that I'm not getting "max-value" of my "downtime" if I'm not consuming the same television show for the upteenth time. I'm also entertained by mindless youtube videos or videogames.

How do I start feeling refreshed/recharged/relaxed by different forms of media?

I want reading a book or watching something educational to feel like entertainment instead of feeling like it's something productive.
