Thaks for all the comments! I always wanted to go into teaching after I gain some experience in industry! Reason, because I love to teach? At least that what I think. I wouldn’t know for sure whether I will survive in a real school environment also.

I heard that mid career switch into teacher would be at least getting 5k? If you friend is getting 5k only 6 years after mid career switch, then maybe the length in industry is not long enough? Or maybe the example I heard was an individual case?
