Again, I observed this on the earth: the race is not always won by the swiftest, the battle is not always won by the strongest; prosperity does not always belong to those who are the wisest, wealth does not always belong to those who are the most discerning, nor does success always come to those with the most knowledge -- for time and chance may overcome them all.

If an iron axhead is blunt and a workman does not sharpen its edge, he must exert a great deal of effort; so wisdom has the advantage of giving success.
