If you are committed to serving yourselves and the world, you must also be committed to a standard of excellence.
Doing excellent work means doing it to the best of your abilities. It means making the wisest use of your available resources. Excellence is putting forth into the world what you consider to be your most loving, most helpful, most impactful efforts at any given moment.
If your aim is continual improvement, which it ought to be, it follows that your work, tactics, and skill sets are always evolving.
The good news is that excellence is not a fixed measure. As you refine your approach, broaden your knowledge base, and call upon the wisdom of past experience to inform decisions of the present, that standard progresses with you.
Your internal measures of excellence are not comparable, then, over time.
What was once your best still represents your best for that moment. It retains its status if it was created with an attitude of love, and it does so regardless of how it compares to the benchmark you are setting now.
Do not confuse your very best of the past for inferiority. Do not confuse your very best of the present for your ultimate capacity.
You will inevitably find better, smarter, faster, Simpler ways of doing things.
Keep focused on what you have and know now, on creating and sharing your gifts, and excellence will be a guide that follows you naturally all your life.
