Don't Look Back, You're Not Going That Way
Letting go embodies the acknowledgment of let down, failure, unattained aspirations, hopes, dreams. At least that's what it feels like. Which is precisely why we make letting go so hard.
When you examine letting go, with some distance, you begin to see how much you participated in creating the end. Unconsciously, we have a natural tendency to drive away discomfort, to drive away that which makes us unhappy. In spite of tenacity, in spite of our fear of failing at something we strive for, we reliably sabotage the things in our lives that are inherently wrong for us. We may hang on like hell. We may resist all instinct that what we're attached to is wrong for us. And we sure as hell mourn the failure of ANYTHING we've worked at.
But, when all is said and done and the wrong has dissolved from our lives, looking back is the only misery. Self-imposed at that.
