Mistakes are inevitable; we are only human, and life is only life. So in order for us to do our best and so meet our destiny to live in utmost harmony with the cosmos, it is paradoxically and ironically necessary for us to embrace and be welcoming of mistakes. By accepting and even 'befriending' the fact of our repeated failures, we free up wasted energy from resisting the inevitable and instead channel it into the present moment to uplift our level of skill in whatever task we are engaged in. We become open to feedback and learning from errors. Thus mastery of life requires understanding how helpful mistakes are, and to even seek them out within the realm of doing one's best, and indeed to see that ultimately there are no flaws in the flow of universal goodness; merely opposites in flux and a damn fine story.
