In his excellent book "The Difference You Make," Pat Williams talks about Coach Bear Bryant and his belief in the importance of character. Here share Bear's thoughts about quitting.
"There's one thing about quitters you have to guard against -- they are contagious. If one boy goes, the chances are he'll take somebody with him, and you don't want that. So when players would start acting that way, I used to pack them up and get them out, or embarrass them or do something to turn them around. The first time you quit, it's hard. The second time, it gets easier. The third time, you don't even have to think about it."
