Save money on the lesson and do it from the comfort and safety of your own home. I use Skype/Gmail in connection with a webcam for online lessons. Regarding the pay: I usually meet my students at least once in person, the first time. I then usually give the student my bank details and they can transfer the money to my account.
I came to Japan because I worked a lot with the Japanese in Australia, as a dive instructor. Since I am a very balanced person, looking for harmony in life, I was attracted to their way of doing things and enjoying the moment.I do not believe in big classes. I limit my lessons to 3 students max. Most of my students know the grammar very well and need to improve their conversational skills, gain confidence. This is achieved, in my experience, by giving the student the opportunity to interact and bring out what lies hidden somewhere in a remote corner of their memory. My favourite way of teaching is to look for interesting articles in newspapers and then read and discuss them together.
