I really liked the idea of creating an emotion. I have been focusing on that in my personal life as well. Last term was very stressful for me because my child was very ill, and I began to notice myself fall into an emotional pattern of worry that bordered on anxiety. I have been working to accept things and to deal with them as they come vs. trying to figure everything out ahead of time.
As far as facial expressions go, it has become a habit to me to smile a lot. I think that is because in dentistry, we try to always be upbeat and positive, no matter what is going on behind the scenes, because patients are generally afraid to be there :)
Even if someone has really ticked me off, if I take a deep breath and smile, I can usually shake off the emotion of frustration, etc.
