@cm If I had to summarize the book, it would be something like:

Declamatory style, sometimes even heavy. Contradictions arise despite the apparent good intentions of the author. Some may object that a successful person urges spiritual answers to those who may be struggling, but he also addresses those who have achieved comfort and yet feel spiritually empty. All those who can stop to contemplate how they could improve their spiritual side will find here much to consider. Brooks's description of the need for spiritual and emotional awakening refers to earlier American writers, such as Horatio Alger, who urged readers to strive for improvement, even if their path was material progress, and Dale Carnegie, who described how to achieve both friends and influence. These themes appear and reappear at regular intervals in various guises, including Brooks's highly effective call to reach the second peak of the mountain.
