Jimmy Johnson, when coaching on the college level, had a wife and the appearance of a marriage because it was expected of college football coaches. The wife and family was needed for social occasions. The day he was named head coach of the Dallas Cowboys, he set about to rid himself of this excess baggage. He threw her away like yesterday's newspaper. He didn't need her any more and he didn't lose any time in losing her. He confessed that he never bought his boys birthday or Christmas presents. He just didn't have the time, and they weren't a priority. So he single-mindedly threw himself into his football team, and in January, 1993, he made it to the top, #1, they won the Super Bowl.
So what's he going to do next year, and the year after that, and (In 1995 he was sacked, lost his job as head coach of the Dallas Cowboys. The last I heard, he's being considered as a TV football commentator. The question he'll have to answer every day of the rest of his life is this, was it worth it?)
