I think school teachers are like farmers. It's a passion of love. You certainly don't do it for the money. Therefore they are not the best Entrepreneurs, IMHO.

In this case, the guy found out something that works. I would keep teaching because that is better than money (for this situation) and I would develop a way (at night and weekends) how to show other teachers the way to make money and subscribe to your model, so you can make the same 6 figures while they do all the work and pay you for your idea.

Isn't that teaching too?

Anyhow, my opinion is that people leave for the immediate gain too quickly and don't think about all the things on the other side.
