That seems like readability is even more important! I've taught programming to friends and family my entire life (to anyone who wants to learn), and one thing I always focus on is 'telling a story with comments', explaining how, where, and why data flows through the code. At the end, reread your comments and your code and figure out which one is wrong; then refactor.
