Pain (any pain–emotional, physical, mental) has a message. The information it has about our life can be remarkably specific, but it usually falls into one of two categories: “We would be more alive if we did more of this,” and, “Life would be more lovely if we did less of that.” Once we get the pain’s message, and follow its advice, the pain goes away.
Peter McWilliams, Life 101

The more severe the pain or illness, the more severe will be the necessary changes. These may involve breaking bad habits, or acquiring some new and better ones.
Peter McWilliams, Life 101

As I see it every day you do one of two things: build health or produce disease in yourself.

Be careful about reading health books. You may die of a misprint.
