For over twenty years, I have been building up a wealth of valuable training material about Sun Tzu’s principles at ScienceOfStrategy.com. However, the primary purpose of its online training was to promote my services in live training. For fifteen years, the corporate customers this site attracted allowed me to travel the world and make good money teaching a system of success that I love. Eventually, it allowed me to build a worldwide network of licensed trainers. Unfortunately, that network ran into a lot of difficulties during the Global Financial Crisis of 2007-8. Not long afterward, a series of health issues prevented me from continuing live training myself.
