Move beyond Judgment.
Knowledge and intellect are awarded with their own price. There is a cost to understanding. If your understanding is not evident in your actions, then it can be a challenge to move beyond your own judgment of your choices. There is "a knowing" and "knowing." The first is housed in the intellect. You get it. It does not mean, however, that you do anything with it. Knowing is the result of experience. You have lived this truth and have an experiential understanding of it.
To categorize ones actions as a "mistake" is a convenient way to avoid responsibility and effective action. Remaining in a place of judgment is common and it serves no one. Every experience will inform you of a more effective way to live your life if you allow it to do so. There is no such thing as a mistake. The worst thing that can happen is that you realize that you could have made a more effective choice given your intention. You may not have known that until you experienced the effect that you (and your choices) caused.
If one chooses to be on the path to greater success and authenticity, one must rid himself/herself of the judgment over ineffective choices/actions. It does not serve you. Apply your greater understanding to a more effective life, which means that the "mistake" served its purpose in bringing you all that you desire.
Success or sabotage? Commit to one or the other. If you invest more in self-judgment and criticism than forward thinking and movement, you are NOT on the path to success.
Is this going to be an incredible day? Choose the kind of day that you want to create--be precise--and DO IT.
