As the title implies, my book discusses the significance of personal development as a key factor in success and happiness. The book is a sort of collection of my most important and useful thoughts and ideas, which will help you to get new insights and make your life little better and happier.

Since this book in intended to be as comprehensible and easy to read as possible, I have tried to express my thoughts as compressed as possible, leaving space for you as a reader to form your own opinions on things. The book will give you ideas and inspiration to go out and explore your own route on self development.

My book is available on Amazon, both as a Kindle and a printed version: amazon.com/gp/product/149446778X?ie=UTF ... =hpco0f-20
