If you have a hobby of teaching. Why do not try to be a teacher volunteer in Cianjur formal or informal schools. You can teach in my ex high school or you can also teach in english course. I have an access to do it all, because i still have a good relationship with all the teachers, especially with English, German, French Teachers. You can share your english or others languages, your culture, or your travel experience with the students.
You can teach them with your own programs and methods. The students will be proud and happy on improving their own english. You do not need an Education Certificate, as long as you are able to speak and write english well, you can teach in Cianjur. You will have a nice travel with them, because they always ask guest overseas to go somewhere.
