Use your Judgment.
We define ourselves in contrast--in relationship to one another and to the effects that we cause. For every action, there is a reaction. When we are able to connect the two and to determine that the results are not aligned with our intention, we make more effective choices. For this reason, the concept of mistakes assumes a judgment that does not serve us. It is merely a way of feeding an ineffective story, where we sit in judgment of one another and (most of all) our selves. By sitting in the position of superiority and proposed wisdom, we sabotage our own growth and feed our propensity for inaction. It is a fertile ground for the illusion of perfectionism and ultimately a form of self-sabotage.
When you find yourself looking at another with disdain, step back and consider what it mirrors in you. Is it a reflection of a current challenge or the memory of past folly? How can you utilize this judgment in inspiring more productive actions in your own life? How can you exercise more compassion in your thoughts, words and actions?
Success or sabotage? If your focus is fixed on what is wrong, how are you going to see what is "right"?
Is this going to be an incredible day? What lessons from yesterday can you use to make this day more joyful?
