The disappointment & heart-break, comes from unsustainable expectations. Born into this grand, evolving experiment, and trying to find a place, a way, a method; developing a code for better living. Long-form improvisation.
Doing the best I can, often falling short. Discovering that every damn thing counts. I am reminded of that nearly every day. Sometimes I am on cruise-control, and then there's the unexpected; a pothole in the road, a dangerous cliff, the impenetrable wall.
Can't take anything for granted. Thinking you're not fucking up, but then finding out you are fucking up. A shock and a wakeup call. Embarrassing & humiliating. How to respond? Wake up. Commit to doing better.
Getting angry & shutting down, they are counter-productive ways of dealing with obstacles. Taking the hit, and keeping on keeping on with eyes wide open is much the better way. There will always be adversity & fuckups. That's just built-in. Just have to deal with it, with heart, grace, humor, and yes, humility.
