No one should ever wish tragedy into their own or other’s lives, but it has the potential to lead to some incredibly beneficial life changes. Chris Kresser transformed a decade long struggle with a rare chronic disease into something that benefits society. He was able to restore himself to health and is now doing the same for others. His main piece of advice, “eat real food,” is deceptively simple until you look at the food trends in American culture and realize that the majority of the people the majority of the time are doing no such thing. It may be the single most important thing you can do for your well being. Kresser explains why.Lessons:    1.    To stay focused, create a pointed mission in life; do everything that delivers you towards that mission, eliminate those things that don’t.    2.    In order to accomplish your goals, you have to be a whole person: if you don’t optimize your physical and mental well being, then you’re not much help to others.    3.    Eat real food. Maximize nutrient dense whole foods and minimize those that come from a box, bag or can or use sugar, white flour or seed oils.
