It sounds like you had a bad experience, but try not to project that on to others.

Nobody suggested teaching or swimming without proper preparation and adequate aerobic fitness. I understand how changing your argument makes it easier to argue against yourself.

Kind of like how in your subsequent paragraph you pretend things were sad that nobody has said in the entire thread except for you.

You don’t have to teach kindergarteners if you don’t want to. It sounds like it you might want to re-examine your choices.

Making up your own arguments and then throwing a tantrum about your own bad ideas is not very convincing.

If your goal is to maximize your time and minimize your work, there are lots of easy ways to do that.

Teaching is one of them.

You seem stuck on teaching, probably because of your profession, but it’s not the only road and you shouldn’t force it on others.

You prefer to minimize your own time.

I help people maximize their time and minimize their work.

Youre naturally defensive, try to recognize that.
