Wise men of ancient times and successful men of today have told us that labor is sweet.

Its reward is not material gain but what one becomes by it.

Work does much more for us than just giving us a living; it gives us our life and the reason for living.

The real joys of life come from doing something and doing it well.
   
All of us hope for success, but it is illusive and hard to keep.

It nearly always slips away from one like sand through the fingers, like water through a leaky  pail, unless it is held

tight by hard work, day by day，night by night, year in year out.

Everyone who fears failure should work harder and harder with a faithful heart as long as he lasts.
