Teaching abroad without proper preparation and understanding of what you’re signing up for is a recipe for culture shock and depression.

Lots of people have the patience for kindergartners, but that’s only because there are eight billion people. Telling everyone who’s depressed to go to a new place where they know no one and have to deal with kindergartners and employers who may or may not fulfill the accommodation or pay promises they made while not having a good working knowledge of the local culture or language is irresponsible.
