Find something that you're really interested in doing in your life. Pursue it, set goals, and commit yourself to excellence. Do the best you can
Excellence is a word that means superior or above and beyond. If you show excellence in decision making then you make very good decisions, and excellence is something that you should expect from yourself if you want to become a better person. It is impossible to achieve excellence in everything that you do but that does not mean that you should not strive for this goal.
