Another thing to look into:
Book lists.
Look over bestseller lists to be current.
When I was young, I got a copy of the Harvard University Book List of required reading for Harvard students. I couldn’t afford Harvard, but I could read all the books!
Another thing you can try is learning languages.
I studied 7 by using the Pimsleur method and combining that with listening to popular music in my target language of the year. I was able to gain fluency in many languages by only listening.
That’s a good idea, though I’m afraid a lot of the books will be liberal propaganda.
