This book is a practical guide to self-development and managing your own life. Awareness of just a few important laws of life can fundamentally change its course. Everyone needs to make the choice of these attitudes, but not everyone realizes the need to make this choice, thereby risking not living their lives. The book that you hold in your hands is a toolkit that allows you to form your own view of yourself, your life and value system, take control of your emotional state and not succumb to the manipulations of other people. It provides an opportunity to build your life in conditions of uncertainty and constant change, establish effective relationships with other people, get rid of worries and fears and feel that you are living the fullest life you can. This book is for those who want to actively create their own world around them and are not ready to play by other people's rules.
