Henry Cloud said this quote
“ Page 99: ...unless something changes, the future that you can expect is more of the past. Sorry or becoming committed does not make Jim Carrey a great golfer, or made Jack nicklaus funny. Recommitment does not make a person who is unsuited for a particular position suited for it all of a sudden. Promises by someone who has a history of letting you down in a relationship mean nothing certain in terms of the future. ”
