Hi Tomo,
I wonder if you have ever considered doing group lessons through GW. These days it seems as if every online guitar teacher has some courses to offer students. I've seen it like GW where people go to a site and watch prerecorded lessons. Examples include places like TrueFire and similar learning sites.
Of course, I've seen teachers offer 1 to 1 lesson, like Tomo does, at of course a much higher price. Unfortunately, I think most people are unable to afford hundreds of dollars an hour to get a lesson.
So, as a compromise, have you thought about doing group lessons and have something in between what is here on GW and what you offer in private lesson? This could be a way to have more students getting direct support a probably a slightly better monthly rate.
Another reason I am asking is that the monthly YT GW sessions are pretty popular and many can get your advice and lessons while interacting with you and others.
I look forward to your thoughts and feelings about this.
Thanks!
