I remember feeling that fear. I remember the first time I was critiqued for my drawings. I remember the first time I was criticized for my songwriting. I remember how I felt. And I also remember how I felt when I did draw, sing, write, create, design, ... pretty much any verb, including dance, play, and even skip. I feel free. I feel alive. I feel creative. And that's because when I do those things, those verbs, I am living in the moment. I am doing what I enjoy, without fear of ridicule, criticism, or judgment. The reality is that I know those are things I can't avoid, but when I'm in the moment I don't think of those crippling things. I just live. And that's what I told her, draw, sketch, do anything just for you. If you enjoy it, do it. And also know that someone will be impacted by your work.
There will be times when you do something just for you with no one ever to see the results of it and there will be times when others will see it. Don't let others' eyes stop you from enjoying the moment.
