Og Mandino 1924 was born in a civilian family in the eastern United States. Before he was 28, he was lucky. He finished his studies, got a job and married a wife. But later, in the face of all kinds of temptations in the world, I made a series of unforgivable mistakes because of my ignorance and blind impulse, and finally lost all my precious things-family, house and work, and was almost poor. So, he began to wander around like a blind man, looking for himself and looking for all kinds of answers to live on.

Two years later, in a church, he met a respected priest. The priest started a dialogue with him and answered many questions that troubled his life. When he left, the priest gave him a Bible. In addition, there is a book list with the title of 1 1. They are: the greatest strength, the treasure land of diamonds, the thinker, challenging you, the autobiography of Benjamin Franklin, the spiritual factors of success, think and grow rich, the sales experience from failure to success, the magical emotional power, the power of love and the power of faith.

Mandino's law is his theory about his life experience and knowledge.
