Excellence is an art won by training and habituation. We do not act rightly because we have virtue or excellence, but we rather have those because we have acted rightly. We are what we repeatedly do. Excellence, then, is not an act but a habit.
Allow your Christian values to guide your actions in everything you do. Fuel your Christian spirit by attending church, joining a bible study, or reading through the scriptures. Do this often and form a habit of becoming more Christ-like in everything you do.
Finally, brothers and sisters, whatever is true, whatever is noble, whatever is right, whatever is pure, whatever is lovely, whatever is admirable—if anything is excellent or praiseworthy—think about such things.
