Take the lesson, leave the baggage

The lessons are what you should do or should NOT do next time based on whether it worked or did not work this time.  

The baggage is the stories you’ll carry around for too long about those lessons.  

Lessons are light and plentiful and objective.

Baggage is heavy and burdensome and judgmental.

Best to take the lessons out and leave the baggage on the curb before it gets heavy enough to slow you down.
