They are not all here, the steps to health and happiness. The reader may even be annoyed and baffled by my indirectness and unwillingness to be specific. That I cannot help—it is a personal peculiarity; I cannot ask any one to live by rule, because I do not believe that rules are binding and final. There must be character behind the rule and then the rule is unnecessary.
All that I have written has doubtless been presented before, in better ways, by wiser men, but I believe that each writer may expect to find his small public, his own particular public who can understand and profit by his teachings, having partly or wholly failed with the others. For that reason I am encouraged to write upon a subject usually shunned by medical men, being assured of at least a small company of friendly readers.
I am grateful to a number of friends and patients who have read the manuscript of the following chapters. These reviewers have been frank and kind and very helpful. I am particularly indebted to Dr. Richard C. Cabot, who has given me much valuable assistance.
