The undisciplined live a life that goes here and there and nowhere.  The disciplined life has a goal and a vision and seeks ways to get there.  It knows that the right roads must be intentionally taken, while avoiding attractive detours.  The undisciplined life allows other people and circumstances to set its agenda.  It is constantly frustrated because of its ambivalence.  Self-discipline is not a bad thing.  It keeps you on track.

“Whoever wishes to save his life will lose it, but whoever loses his life for My sake, he is the one who will save it.” Luke 9:24 (NASB)
