Things that led for Nikola Tesla to become a great inventor

Tesla carried the guilt of his brother’s death since he was a little kid. This guilt led him to a Spartan discipline that he created himself. He trained his memory and telepathy by captivating by visual memory every smallest detail. His first contact with electricity was at the time he was three. He pulled back his tomcat by the tail, and he bathed in light. "Is nature one large cat? If it is, who is pulling her by the tail? It can only be God." concluded Tesla. Maybe this experience later led Tesla to become a famous inventor.
