Have you ever worked for or led an organization that accomplished great things?
After things fall apart, you continue to look for ways to recreate the magic in the following years. You try a bunch of stuff, but nothing works.
You turn to the folks who shared that magic all those years ago, and try to get the band back together again.
But you know what? Almost 100% of the time, you can never go back.
And the more you cling to it, the more disappointed you become.
Sometimes it's better to move on and try to create something different - the magic may not be the same ... but success in almost any form is always sweet.
