No correlation
A fact that provokes: There is no correlation between dealing with anxiety and getting things done that are worth doing.
Many performers feel debilitating anxiety just before the show, every time. Some have had panic attacks while performing, ending that specific show. Yet they are still doing shows.
Some people live with, over, and around their anxiety and still get it done. Others cannot. Still others need some fear to move away from.
There is something to learn from this, and it starts with realising that not everyone have the same experiences.
