This document discusses being proactive versus being reactive. It defines proactivity as taking steps to solve problems before they become issues by avoiding problems in the first place. Proactive people take initiative, do not limit themselves, and can control their character and reaction to circumstances even if they can't control the circumstances. Reactive people blame outside factors for their behavior rather than taking responsibility for their own choices and reactions. The document encourages the reader to be proactive by choosing to have a positive attitude, focusing on things they can control like their mood and treatment of others.
