Discipline is the refining fire by which talent becomes ability. (Roy L. Smith, American animator and film director)
To a lot of people the word “discipline” brings thoughts of punishment. Yet, its basic meaning has to do with training. Though training may be difficulty (think training for the Olympics) its purpose may be to correct errors, or to strengthen and improve skills. For that reason we should welcome any discipline that will make us more effective or skillful.
No discipline seems pleasant at the time, but painful. Later on, however, it produces a harvest of righteousness and peace for those who have been trained by it. (Hebrews 12:11).
