I am doing this too, with Macdonald's "Linear and Geometric Algebra" and "Vector and Geometric Calculus" along with "Networks, Crowds, and Markets" and "Chaos and Nonlinear Dynamics." It's slow going, but very enjoyable. The most interesting side effect I've noticed from doing this is a dramatic improvement in my ability to focus. I had been suffering from a general scatterbrained, distracted feeling for a while before I started. I think it was due to the way I consume content online, trying to follow too many interests at once. I set aside about an hour a night to work on these math courses and within a couple of weeks I noticed that my focus was greatly improved. For that reason alone I'm counting this project as a major win, regardless of whether I master these topics or not. Having something to study seems to be extremely valuable for general mental health, at least for me.
