Critique on Dale Carnegie's "How to Win Friends and Influence People" - A Study on Application and Misapplication of Principles

Whether a successful person knew them or practices them or not he is successful despite his no knowledge or practice of these principles. In other words, these principles add charm and shine but they are not the essential factors to lead you to success and place you in higher places.
These principles are impotent and have limitations. They are not universally effective, not absolute, they do not work with all and sundry, always.
It was also observed that people who have the knowledge of Dale's principles just know it for knowledge sake and keep without practicing them. They fully subscribe to the wild ways of the world instead of practicing Dale as and when possible. Wild world is so powerful over these principles. Wild world so far has dodged all technics, tips, tricks, principles and rules the wise have known and taught. It suggests that to handle the wild world tricks, technics, principles and rules won't do. Something else is required.
Since the time of knowing and practicing Dale the author had this insight that social interaction, interest, rapport, liking, etc., are not based or caused, not generated or created solely by the tips, tricks and technics or principles of Dale or anyone else. Rapport and liking are something mysterious. It may be chemistry or something esoteric. Tricks and principles play only supporting role to this unknown mystery. Tricks and principles will not establish rapport and rapport exists without tricks and principles. Liking and rapport are something very deep at gut level. No amount of tricks and principles can bring this liking and rapport.
The three wise things are: practicing Dale, getting along well with those who are ignorant of Dale and are contrary to Dale, and also feeling good with those practicing Dale.
