I have a mere 10y of experience, but also already looking for 1 year and also considering maybe I should become a teacher. Dealing with unruly children might be nerve wracking, and the tech level will be very basic, but I have always enjoyed enabling others to understand things and see them grow and having done my part in that. Also solid well taught foundations are very important. Currently, my only obstacle is, that it is not so easy to become a teacher where I live. Certain requirements kind of like certifications, that you can't just easily get, but need to invest a lot of time into.
Good to read of someone, who went that way. How did you manage the transition?
