Hey man, great post. I knew about Kaizen but loved the way the video explained it. It reminds me of the Jeff Olson book the Slight Edge which is a similar concept of tiny almost imperceptible improvements daily that over time compound into incredible results. Also the Compound Effect. :)
Where in Costa Rica are you? I go to Avellanas a lot to visit family and will be in Tamarindo for a Jiu Jitsu seminar in a few months. Pura vida!
