From The Still

Mutterings like honeydew vine water.
Don’t talk yourself into not being you at any time. You don’t have an excuse that works; when you say, “But, i was nervous.” That’s not you. That’s not how you got here. Yeah, you can be nervous; it’s good for you; tunes you. but people want to see you. I don’t care what you do. When you’re good, then you bring YOU out.
