In the form of a letter to his young son, a father explains the rules he has learned from his own and other's experiences, for a successful life. Simple, straight-forward commonsense, nothing to take exception to, for it is essentially conservative, dealing with the problems of deciding on a vocation, marriage and the girl, consideration for others, friends, and good advice as to honesty, decency and tolerance. Basic theories of right living, rather than factual content on handling of such things as sex and moral codes. Theory -- backed up with anecdotal material. Intended for prep school age or college, though written for an eight year old to read when he grows up to it. Good reading for fathers who are puzzled as to how to put over this sort of thing to their sons.
