Perhaps the most important and amazing book of the century?
The ultimate book of self-development. With the necessary maps and tools, exercises and techniques that will make you able to break down seemingly complex behaviour into digestible chunks. Not only will your level of awareness never be the same again, but you will be able to create change, knowing where you come from, where you are, where you want to go, and why.
Serious, but also both witty and provocative, this book is what you need to develop a mature and balanced Ego, and also to choose what a include in your world - and what to keep out. There is also a part analysing the world we are living in, dealing especially with how we are manipulated by and accepting the mental designs of others: Beliefs, ideologies and world views that not always have been created with your best interests in mind, and cultural influences that should have been removed to the garbage dump a long time ago.
As a bonus, you will probably be vaccinated against political correctness forever!
