“This inclination to ignore problems is once again a simple manifestation of an unwillingness to delay gratification. Confronting problems is, as I have said, painful. To willingly confront a problem early, before we are forced to confront it by circumstances, means to put aside something pleasant or less painful for something more painful. It is choosing to suffer now in the hope of future gratification rather than choosing to continue present gratification in the hope that future suffering will not be necessary.”
