Giving up on materialism

Of late I have been reading a lot of books on quantum physics, spirituality and leadership. I have read your books as well and in fact keep reading them repetitively. The more I think and ponder, the more I am convinced that the path to true joy and happiness is through living with less and giving up on materialistic attitude. I teach leadership and systems thinking approaches to Corporations and teenagers. My question is “How do I tell my CEO’s and Teens to pursue their goals of growth and prosperity on a material plane and yet teach them to live a simple, selfless life? The more I wish to grow the more I wish to give away my material wealth. I am caught in this duality and ambiguity. Am I being a hypocrite?
