At the time, I was living with a little family, and I felt pretty bad having to hole myself up in my room for three weeks just poring over the Bach flute sonata. I must have looked insane to them. I actually have a few videos from my time there... I have no idea where I found the time to make videos WHILE dealing with the oral defense, graduation recital, and a host of other graduation responsibilities.
The work is long and arduous, but gosh darn it, it is WELL worth the time and energy you put into it! I really suggest that you try doing the same thing (maybe on a smaller scale, for time's sake) for the pieces that you're studying! It really adds that extra dimension of life, relatability, and feeling of ownership when you're performing the piece.
Happy studying! <3
