"One of the most important improv lessons I've learned is that any "mistake" you or your scene partner makes can almost always be a gift. That has often become the fun unusual thing in the scene that we get to play with and ends up making the scene funnier and more enjoyable. It can be so easy to try to be a "perfect" improviser who gets everything right but in actuality curiosity over perfection will always help in the long run. So if you ever think to yourself "Oh no! I just messed up!": Take a breath and think about what this could possibly mean for the scene. Allow yourself to be surprised by yourself and I assure you the scene will be way more fun and interesting."
