Welcome!
Let me just say - whoever has been homeschooling you has apparently done a fine job of getting you to think about learning "about learning" itself. You came here asked that question. That's a big dern deal..
So good on somebody!
I didn't get much from some of the required reading and if you're not going to discuss them, then 1984 and Animal Farm and Catcher in the Rye and others of that ilk are of less value I think.
This is what I'd recommend along with others suggestions.
The Declaration of Independence
Homer's The Odyssey and The Illiad
Poems of Milton
Sir Walter Scott's Ivanhoe
Marcus Aurelius The Meditations
Albert Camus The Stranger
Rudyard Kipling The Jungle Books (1 & 2)
Bulfinch's Mythology (3 vols/ages)
Charles Darwin's The Voyage of the Beagle
John Locke's Essays, particularly about Education
Francis Bacon - Essays Civil and Moral
Travels of Marco Polo
The Bhagavad-Gita
New Testament of the Bible (Mathew, Mark, Luke, John and Acts at least)
The Koran
Buddhist Writings (I don't remember what exactly I read)
Shakespeare's Richard III & Henry VI and as least 1 of the comedies
King Arthur and His Knights (pick a version, I've read the original Mallory but I don't recommend it to start, also enjoyed John Steinbeck's and Roger Green's versions as an adult and Howard Pyle's and Henry Frith's as a child.
John Steinbeck's Of Mice and Men
Oscar Wilde's The Importance of Being Earnest
Machiavelli's The Prince
Gustave Flaubert's Madame Bovary
William Golding's Lord of the Flies.
Victor Hugo's Toilers of the Sea
Aldous Huxley's Brave New world
Dorothy Sayer's essay The Lost Tools of Learning
And after those, I'll follow through with
Animal Farm
George Orwell's 1984
Michael Crichton's Jurassic Park
William Manchester's The Glory and The Dream
David McCullough's John Adams
David Halberstam's The Best and the Brightest
And if you want an interesting little book about how
things work, read Eliayahu Goldratt's book The Goal
which is a novel approach to learning about
cause and effect.
