The key takeaway I had from that course was "money can solve more problems than you think, so it should be the first problem-solving strategy that you consider". This was pretty counter-intuitive in college, when I always felt like I didn't have enough money, but just knowing that this was a possible way of solving many classes of problems changed the way I approached decision-making in my later life (e.g. when picking my first job out of college).
