Mindfulness is such an important practice. I agree, with the right attitude every experience has the potential to become a learning experience. We can't always predict an outcome, but we can at least know our intent. And yes, we can't always fix our mistakes, but, we can still change our mindset moving forward. Yes, finding acceptance is tremendously important. So many people endlessly torment themselves for the mistakes they have made, so much so that it impairs their ability to move forward. Life can be very challenging at times.
