Query: Short, yet powerful

This classic book is short in pages, but contains a lot of strong ideas from old Toltecs, which have both soothing and empowering effect. The four agreements (there is no need to repeat them here as it has be done in many other reviews) together make compact package and I believe they create a very solid foundation of a philosophy for whole life.Most interesting topics/ideas for me:- How our opinions are formed during childhood and how we grow up used to doing things to please others and forgetting about our own desires.- Clear communication (I want this, you want this, let's solve it) solves most of (all?) problems.- Our harmful words damage more us than they damage those for whom they were intended originally.If the topics were discussed a little more deeply, I would give it 5 stars...this way I give four.
