Learning isn't a tedious process. It can be as simple as saying "hey, how does that work" or "what are you doing" to someone working. I think talking to people, or thinking through how things work is relaxing.

Also there is no reason why you can't rest. We dedicate ~8hr/day of our lives to resting. We also get full days on weekends. We also get about 7-12hr/day for doing whatever we want while awake.

In those 7-12hr you can sit and stare into the idiot box and laugh when the talking heads tell you to laugh or you can read a book, go out side, think about "how would I make X", prototype some code for doing something, talk to some people who are professionals in a craft and ask "how do you build X".

I think one is way more fun then the other.

Now don't get me wrong, I watch a lot of TV but most of the TV I watch is "What If". I like science fiction stuff and a lot of it is some social commentary put into a setting that makes it ok to talk about or even asking moral questions that are different all together. Thinking about those dilemas falls under the classification of "learning". This isn't technical knowladge but instead social.
