That intense study period I suppose is somewhat "Te"? Maybe? I know I could get better at music by adding more of the Te approach, but I don't. I had more of that approach when I was younger.. I never practiced exercises much, but I'd dedicate myself to learn certain songs. Kind of like rites of passage or something before I could wing it. Kind of modest goals on that end, I guess.
I'd like to do this with training actually. Learn fundamentals, and I think I could probably learn as I go along.
