This book, unlike some other books, instead of teaching a particular skill (e.g. how to be a good accountant, how to drive a car, how to run a business, etc.) helps develop the attitude for accomplishing any good undertaking, including studying and working. This is important in the modern world where people encounter all kinds of obstacles and sometimes all that they need is a reminder about God's love, the importance of courage in achieving positive results and how to be happy. The title of this book is inspired by Mt 17:20 and Mk 11: 23 (the Bible).
