> I have friends who complain that they are engineers, and had to take so much math in school they don’t use. This seems to me like saying "I could be a better engineer by combining engineering expertise with mathematical knowledge, and I have that knowledge, but I prefer not to use it." I don't always learn new things well enough to realize their potential, but I've never once regretted learning something new, and, if I don't know how to use it, then I usually assume that's on me, not on the subject.
