Maybe I had it perfectly memorized but I got stuck. Maybe I prepared for hours but I got stuck. Maybe I never saw this question coming and I got stuck. About the only way to never get stuck is to never leave home and if you never leave home then, you are stuck. So, what can I do when I get stuck?
Spontaneity is the spark that ignites creativity. Spontaneous action comes from the limbic system. The limbic system is a set of structures in the brain that deal with emotions and memory. A lot of spontaneous action comes from the limbic system. So, action matters. One thing you can do when you get stuck is move. To the degree possible, move in the context you are stuck in. Stuck telling a story? Put the story in action. Stuck because you are speaking to a large crowd from the front of the room? Move to the back of the room.
What can you do when you get stuck? Get spontaneous.
What is one way to get spontaneous? Action.
