That's the best advice!
My parents homeschooled me with a massive home library (the whole clan, all bibliophiles). I had kid books that dated back to the 19th c! Old textbooks. Old encyclopedias. No tv or movies except what they carefully selected, and of course I was allowed some access to the computer, but I grew up with the mindset of the early 20th c.
I would add that while it's a thrill to get a magazine in the mail, it's more fun to get a visit from a grandparent bringing a learning experience -- a book, a building set, a musical instrument or a telescope or a radio kit...
Ah yes, I remember Radio Shack. In the 1970s, my friend's older brother was an audiophile who built his own stereo speakers.
