I've been teaching children two times before to finance my trips around South America. First time was in Peru, and a few years later in Paraguay where I had the pleasure of teaching young kids in math. It's was very challenging as I'm not fluent in Spanish, which made me struggle a bit when communicating with both the children and school administration. But I like to teach, and that's the main thing
It went well, and I feel I got a lot of good experience from the jobs. I can recommend working abroad if you don't mind the language barrier.
