The greatest athletes, philosophers, artists, and business owners of the world all of one major thing in common: they learned the rules of excellence, they obeyed them, and they became masters. If you want to become successful in your life, if you want your relationships to flourish, all we have to do is learn the rules of excellent living and follow them! Fortunately for us, God spells it all out for us in the book of Deuteronomy.
