I found that quote in a strangely-translated instruction manual for an obscure but beautiful trick.
But it has wide applicability.
Perhaps your anxiety is specific to artists or musicians or to anyone who has to stand up and stand out and stand for something.
It turns out that your anxiety isn’t specific at all. Perhaps it is due to the fact that you’re trying to control things that you can’t possibly control.
Your anxiety might merely be a sign that you care deeply about your work.
Anxiety is almost never a useful emotion to carry around. Even for magicians.
Now that you’ve been reminded that you care, it pays to let the anxiety go. Good riddance.
