If you want to change the world, start by making your bed!  Maybe you've heard Admiral William McRaven's speech (https://www.youtube.com/watch?v=3sK3wJAxGfs) where he talks about how making your bed each day can help you change the world.  How starting the day with a  simple routine helps you begin to accomplish all the bigger tasks in the day.  How do you start your day as a principal?  What routines do you do or do you have your team doing that set the day in motion?  That build the momentum for success?  I have two I recommend:  A Morning Memo, and A Morning Meeting.  In this podcast I share a little bit about each.
