[thanatropism]

As a teenager I thought I was bad at math and even went to get a film studies/communications bachelors (I've defended this week my masters thesis in computational mathematical physical; this after an undegraduare degree in econ with lots of math of course).

The thing is, I couldn't write the damn matrices well lined up and made mistakes when doing calculations. This was really a (de)formative experience. In college Linear Algebra for econ was 40% gaussian elimination, 40% eigenvalues and 20% linear programming. I mean, I still can't do gausian elimination by hand right.

I started crawling out of it when I started seeing (in self-study) a book on linear algebra that takes the linear transform/vector space-first approach.
