Although I missed a day in my journal, I did indeed complete the 30 days of practice.
I have learned that I wish to continue in this manner for at least a year!
Also, I feel better about myself if I am doing at least one hour (or so) continuously, at the same time every day. That would be a powerful practice, which would be good for me.
The only thing I have let get in the way of the quality of my practice, is lack of sleep. I have sometimes failed to go to bed as early as I should, and this makes my vocal practice much less fruitful.
Learning, learning, learning. . .
