I could never get into Farnam Street because it just seemed like appropriating Charlie Munger's mental models to sell self-help services.

I'm more intrigued by something like Online Great Books (https://onlinegreatbooks.com/) which seems like a lot of effort but would probably force me to widen my knowledge - In reality, I wish something like Online Great Books included some first principles math/science books to round it out more beyond the philosophy/literature bent.
