I am also a teacher in a training institution, and I think the key is myself. I am the root of all problems. If you can get a high salary in the training class and teach every student well, that is a kind of ability, which is not bad.

If you really want to go back, such as taking care of your parents and doing something you have to do, there is no way. If there is nothing very necessary, I think it is the same everywhere.

No matter where you are, tapping your own resources and upgrading yourself is the best way home.
