In this article Harrison talks about the external and internal world. We have some–but certainly nowhere near total control over what happens in the external world. However, we do have control over the internal world. The internal world is comprised of our own emotions, how we think and feel about those events that occur in the external world. It is important that we do everything within our power to control our internal worlds. We should guard our internal world and take care to use it for ourselves, and not against ourselves. Problems are always going to be there. You can’t always stop them. What you can control, however, is your response to the problems that come up. Your nature of response is a key indicator to your control over your internal world and ultimately to your happiness and well being.
