The more simple the solution, the better the solution is

I love the 2 points the Air Force shared in this post: What is the Secret for Continuous Improvement?.  Their "formula" is simple, yet powerful.  I have done this with my youth group for years: we review each of their activities after the fact to make sure they achieved their intended purpose.  As we plan subsequent activities and service projects, we incorporate our learnings from earlier.  I also remind the youth there is no one way to be successful.
