This is one of those insights that has had significant impact on me. We often needlessly tie our present decisions to our past mistakes. The thought of "this is just the way it is" or "this is who I am" can be fatal to relationships, goals, and dreams. This thought prompts me immediately to be a better husband, father, and teacher. It has spurred me to act instead of just allowing "the usual" to happen. I hope you'll take some time and allow this one to sink into your heart.
