To make things is to become emotionally involved. I’m not sure it’s possible to be dispassionate and produce things that are worth a damn. But my main concern with losing it is to find ways beyond or out of that state.
Breathing is always good for centering. Centering is the practice of withdrawing your attention back inside yourself. When you feel scattered and stretched, if you can pull back emotionally, you’ll feel better able to cope. It’s an easy borrow from meditation: close your eyes, take a deep breath, hold it for a half-second, let out the breath, wait a couple seconds, open your eyes. Sometimes that’s literally all it takes to become calmer and more focused.
Don’t take my word for it, it’s classic Karate Kid!
