I began to read, and there was some kind of annoyance- another guru who "teaches" how to live, with emphasis on the fact that the main success in life- it material welfare.
But anyway I read it to the end. I have liked some thoughts. In general, I believe, that this book can be in something useful for a particular age group, from 16 years to 30 something’s. It is directed to those who live in relatively favorable conditions, where there is no war.
