When I founded NAMC 20 years ago, I simply had one idea that I thought could work. Two decades later, NAMC has grown to include Montessorians around the world and I have had the benefit of numerous life lessons. As part of NAMC’s anniversary celebration, I have been asked to share 20 lessons that stand out in my experience of providing Montessori teacher training programs worldwide over the past 20 years. This is the first of our series. I hope you find some of these ideas helpful in your own Montessori journey!
