Careful, you might get yourself into edtech. >-D
The average career length for teachers (not job, career) is 5 years and trending down.
The reason is not a secret: teaching is a brutal experience with sub-poverty wages. In most cases parents, students and the school administration are your adversaries. If it’s a public institution, political campaigns come crashing in annually with “us vs them” battles that make it awful no matter what side you are on.
It is not a job anyone should pursue.
