The constant discovery of new techniques and technologies and the rediscovery, and different, creative applications of existing techniques and technologies to the art of theatre.
Seeing students discover and develop talents and skills other than of what they thought they were capable. In teaching technical production, I find students often discover a range of skills and abilities useful beyond theatre making.
I love to sail. On the surface, the unpredictable chance associated with sailing and the detailed organization required to open a play on time would seem incompatible. But in reality, making theatre is a lot like sailing.
Conditions often change quickly and there are a lot of discoveries to be made in the moment. So, you have to take control of the things that you can control. Otherwise, you will never be able to respond to the unexpected. There are a lot of life lessons in sailing and theatre-making. Connections abound. The first theatre riggers were tars. Therefore, the reason that you are never to whistle on stage is because whistles are used on ships to signal changes in the rigging. I don't want scenery coming down on my head.
