This book is dedicated to all you teachers and parents who work day and night for the children. Sometimes it happens that you neither see the day nor the night just work for the future of the children. Whoever is the source of my inspiration, I will not name them, but I will be grateful to them throughout my life that they become my courage in this holy work and become my step in making this book complete. This book draws positive and positive lessons from the experiences of the eleven years I spent with children. The strength of negative results is learned on the basis of analysis.
