A prospectively lucrative replay of three of Peterson's collections of doodah maxims for living--which cover a welter of abstract nouns in everyday or gerund form having to do with existing beautifully. From the ""Art of Awareness"": ""It is searching for beauty everywhere, in a flower, a mountain, a machine, a sonnet and a symphony."" For those searching for beauty in a buck, there's the ""Art of Selling"": ""Let's roll out the red carpet for the most important person in the world--the customer."" Then again, ""Words are the pegs on which we hang creative ideas."" Ask not the reason why. . . .
