Do what you can
With what you have.
I fell out of my vocal practice over the week. It's something that I'm really good about maintaining when I'm at home (Boston), but not good at when I go away, which is something I really need to get better about.
I almost didn't practice, but then I remembered that even 10 minutes would serve me better than zero minutes.
I would love to tell you that I'm perfect when it comes to my routines, but I am not. But I'm working on it.
