For a long time, I thought I would like to be a doctor. Such a good profession. So explicitly good. Never a waste of time.
For me, one of the important things about keeping vocally healthy is warming up and making sure I'm aware where my voice is at, drinking lots of water and getting plenty of sleep, and just taking care of myself with exercise and eating healthy.
But I think one of the reasons I tend to stay in the water most of the time is I distrust the comfort.
