according to the history books, its a case of some serious misunderstandings.
When Kashyapa had asked his dad to give him his inheritance ("Dayada"), the dad being a bit of learned man, took him to a tank that he had built for irrigation purposes , and told him that this (the tank) was his inheritance ("dayada" ).

Fear is a damn good motivator as well. Fear made the V1 and V2 rockets, Made the engineering master piece - the Tiger Tank, heck, it made the bomb.
