Becky Robbins, wife of motivational titan Tony Robbins, has been motivated by irreconcilable differences to file for divorce, reports PEOPLE. Robbins, whose battery of self-help books include "Awaken the Giant Within" (a sort of play on words, given Robbins's impressive height), was one of the first motivational gurus to exploit the infomercial market. His keys to success are meant not only to improve one's bank account, but one's personal life, as well. Robbins and his wife were married for 15 years.
