Bill Connolly, Author of The Success Disconnect, explains how improv can be applied to your business - one of the basic tenants of improv "Yes And" - where you just keep going with the flow. This makes people relax and there are no mistakes.
In business - we hear a lot of no. "No we do not have enough time, it's a stupid idea, we don't have enough resources." With business, you should say yes to things, and figure out what they could mean later. Figure out how you would get them done later or saying yes to things might take you down a different path that leads to great opportunities.
