Millman has divided his book into twenty-five short sections. Each section begins with a general question about life, such as "why do I sometimes cause problems while doing what I feel is right?" These are answered with one of the House Rules, such as "Timing is Everything." An explanation of the House Rule and how it may be applied follows.

After that comes two specific questions people have asked him on subjects as varied as free will, metaphysics, child rearing, health, and money. He answers these with practical examples, often using his own life, or with illuminating anecdotes and parables. Many of his answers include humor along with the insights.

He finishes each section with "personal applications" in which people are encouraged to complete two or three simple exercises designed "to test these House Rules in your own experience; tailor them to fit your particular circumstances."

While he isn't a channeler, Millman does say that his answers come through him, not from him. He also says he isn't giving people wisdom that they don't already have, instead he's helping them search within for their own truths.

"In Living On Purpose, Dan Millman combines the wisdom of Solomon with the common sense touch of Dear Abby, taking on real-world questions with the insight and knowledge that have drawn millions of readers to his books." It's an essential reference for anyone seeking practical guidance in answering the difficult questions faced every day.
