Clint, loved reading this!
Sometimes, worry can stop my maker's high in it's tracks. When someone feels unconditional love, oxytocin is released and "all is well with the world". I think that perhaps we release oxytocin when we feel that high.

Conversely, fear releases adrenaline and other brain chemicals that prevent oxytocin from doing it's job. It's been proven that fear cannot be felt while the brain is filled with oxytocin (the feeling of giving or receiving unconditional love).

So, your blog here reminds me that I really need to set myself up for the zone when approaching a work session. If I start to worry about making a great work or art or who will buy it while I'm working on it, I'll never get into that zone. When I'm in the zone, I feel confidence, like I can fly.
Music helps!
