Tomo-san and George may have a different answer, but please allow me to tell a story about learning . . .
In the 1990's I had no idea what Wide Area Networking (WAN) over fiberoptic cable meant.
Our company had a meeting every Wednesday at 8:00 PM where everyone in the company was encouraged to attend. The subject of these weekly meetings was Wide Area Networking (WAN) over fiberoptic cable.
At first, I had limited knowledge of what everyone was talking about. But I kept coming back, week after week and absorbing new knowledge each time. I didn't worry about knowing everything at once or if I was learning everything in the proper order.
Eventually, I learned enough that I was able to help people at a professional level.
We all have an opportunity here to do the same thing here at Tomo Fujita Music.
Just wade into the lessons. If you don't understand completely the first time you watch a video, that's ok. Just relax, be kind to yourself and go back and view the lesson again. Tomo-san also lets you know which lessons might be helpful to you in order to better understand the lesson you are watching.
The bottom line is to watch every day (or three days each week or so) so that you remain immersed in the subject matter and continue to pick up new information along the way to use in your journey.
I hope this helps.
