Insights are the ideas that you get that open up a world of possibilities. It's when you finally understand something. The good interesting thing about insights is that you can get them just about anyplace and anytime. So be ready for them and be looking for them. It is also a good idea to carry around a way to capture the insights you have. It is a good idea to have a notebook or your favorite electronic device handy.
