Excellence

"Tentative efforts lead to tentative outcomes. Therefore give yourself fully to your endeavors. Decide to construct your character through excellent actions and determine to pay the price for a worthy goal. The trials you encounter will introduce you to your strengths. Remain steadfast… and one day you will build something that endures; something worthy of your potential."
                                                                                               Epictetus,
                                                                                                                             Roman Teacher and Philosopher 55-135 A.D.
    Excellence is the result of caring more than others think is wise, risking more than others think is safe, dreaming more than others think is practical, and expecting more than others think is possible. It is the commitment to high quality performance that produces outstanding results of lasting value. Excellence is believing in continuous improvement and never being satisfied with anything being less than it can be. It is quality as a way of life.
