Thanks for the reply, and I know I'm replying ~a day late to your comment.

The near-term costs vs. the long-term payoffs of learning the math skills I was learning were pretty clear (immediate costs, opaque long-term benefits other than being better at math in a general sense). I didn't have anywhere to apply the math, so I decided to spend my time learning more from sources like "Structure and Interpretation of Computer Programs", which is zero-cost to me.

I don't drink any $6 drinks of any sort; I also can't go back to change how much I did or didn't pay for a university education that did or didn't involve learning math for my major.

Other commenters I read who shared price concerns also didn't mention their latte habits or cost of their advanced degrees, so I didn't find this comment very helpful for making that comparison in my specific case.
