This is from a blog post by our friend, Nilofer Merchant, author of the new book The New How: Creating Business Solutions Through Collaborative Strategy:
The challenge with people feeling powerless is this: we don’t see how we can contribute to solve problems. We believe it is “someone else’s” to own rather than something any of us can contribute to. Powerlessness leads to apathy on global issues and disdain on local issues.
Now check out this from Mick Napier’s classic book, Improvise: Scene from the Inside Out:
Two people…staring at each other and wondering who’s going to make the first move. Two people being nice to each other and allowing the other to start doing something. In that short amount of time, two humans have created themselves as powerless…Who has time? The audience is waiting. They don’t care about your support. They care about what you do. What you do now.
These two statements, made miles and years apart, reflect the timelessness of the concept: Do something! Participate! Add to the conversation! When you’re just getting started don’t worry about what the solution will be, or where the scene will take you. No one knows, and your audience doesn’t care. The most important thing is to bring to the scene whatever you’ve got.
The saying in improvisation is ‘take care of yourself first.’ This is not the same as being selfish. It is, rather, the recognition that making the first move, even if we are not always the one to make it, is always our responsibility.

Here are a few of the sayings from what I call ‘Vaillancourt’s List’, with my comments following. As you go about your business, keep these concepts in play:
