" A river cuts through a rock, not because of its power, but its persistence."

Success does not happen by pushing against the obstacles one time. Success happens when your desire to reach your goals are so strong that you keep pushing until you make it.

Discipline is: " The ability to make yourself do what you should do, when you should do it, whether you feel like it or not." -- Elbert Hubbard

Persistence  is discipline in action !
