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

Excellence is an art won by training and babituation. We are what we repeatedly do. Excellence, then, is not an act but a habit.

--Aristotle
