I am a high school math and science teacher, and in the last year I have started to teach an Intro to Programming class, based on Python. It has been really satisfying, and students are loving it. Students are just now starting to understand enough to see where they might go with this.

I quickly run into an interesting problem, though. To teach this well, I am starting to learn the skills needed to work at a startup. That makes me look a little more closely every month at the "who is hiring" post, and wonder if I could leave teaching and double my salary.

This is part of the reason many people who are teaching programming in schools aren't good developers; if they are, it's too tempting to leave and make good money.
