My point is really quite simple. There are beginnings -
And there are endings. As painful or embarassing as they can be, we need to accept the endings. And move on. Respect the past for what it was, try not to repeat the mistakes - but keep moving.
I realize this may seem somewhat simplistic but frankly so is the notion of acceptance. Do everything in your power to get your desired result in any circumstance but when the time comes - accept reality. Go down kicking and screaming if you must but accept reality. And of course it's a blinding flash of the obvious that occasionally some herculean efforts generate results that defy the odds. Maybe you'll get lucky.
On a personal level, we all have traits that identify and describe us. Me? I'm a multi-X in front of the L certified smart ass. I've accepted the fact that skinny and handsome are never gonna be traits ascribed to my overly verbose self. Saves me an enormous amount of mirror time. But like the Beatles said, I'm a clean old man. A mouthy but clean old man.
At the end of the day - with any luck at all, we can all be in this place more often than not - and that is my wish for us all...
