I just love this post. First of all, I’m gobsmacked that you — one of the most respected data scientists in the world — did so poorly in math in high school, and only later fell in love with it. Second, I think your story underscores how incredibly valuable community colleges are. And third, it’s clear you had some excellent parental guidance. Your dad’s focus on having many alternate plans was (and is) really wise. Much respect to your father!
