Nervous, wondering if I would "fit in", what kind of people would be at the training, am I competent to meet the expectations of the assignment. All kinds of things and ideas come up when we step out of our comfort zones. After all it hasn't always been safe to make mistakes in my world. Sometimes there were intensely painful consequences when I made mistakes. And I lived in denial that they were mistakes. Honestly, maybe they were simply a means of rebalancing a system of learning. When I set out to learn a new skill I tend to become intensely focused on mastering that particular process or material. And then, as I gain confidence in my ability to exercise the new material, I relax with it, and enjoy the process, taking in more of the subtle nuances and integrating my new skill with other, older skills.
