I'm a U.S. citizen who does 1 hour of linear algebra first thing in the morning, when I'm not getting crushed by PhD-related deadlines. Currently working through Lang's _Linear Algebra_ for a new take on the material.

(side note: for the first 5 months of 2023 I did 1.5 hours a day of real analysis. I'll probably get back to doing that after getting through most of Lang.)

Can you give me a hint of the types of employers I should be looking for who would value this? How should I go about finding them?
