Something I learned in the Marine Corps that I've applied to acting is, one, taking direction, and then working with a group of people to accomplish a mission and knowing your role within that team.
In every union roles are assumed, some traditional, some not. My husband used to pay his own bills, I used to call my own repairman. But as marriages progress, you surrender areas of your own competence, often without even knowing it.
Waiting is painful. Forgetting is painful. But not knowing which to do is the worse kind of suffering.
Role model? I don't have one. I want to be one.
Your mind is nirvana.
