Not allow myself to be so spooked by freshman Calculus that I switched to the least-technical major possible (American Studies), and ultimately dropped out of Stanford after two years. Now I'm 12 years in to an accidental career as a software engineer. I often think about going back to get a Computer Science degree, but there isn't any point at this level of seniority; it would just be for the love of learning. That feels like too big of a luxury for a guy nearing 40 with a family.
