I am retired early, but I sometimes part-time work as a sign language instructor.
I do this not for a living, just for fun.It is fun to try to explain things in a way that is easy to understand, and I am happy when students make progress.

The hourly income is good, but I also have to prepare before class and have regular meetings, so overall, it is not a good job for me.

But it is fun, so I plan to keep doing it.
