Whatever your life's work is, do it well. A man should do his job so well that the living, the dead, and the unborn could do it no better.
--Martin Luther King, Jr.
If you are going to achieve excellence in big things, you develop the habit in little matters. Excellence is not an exception, it is a prevailing attitude.
Being excellent is liberating and empowering. We are all designed and destined for excellence through all aspects of our lives. Being excellent builds on itself. Starting in the morning, be excellent at preparing for your day. Be excellent at your commute. Be excellent at how you buy your morning coffee. Be in the habit of being consciously aware of how you are performing each task. If you are in the habit of going through the motions in how you conduct the smaller mundane things, it has a way of creeping into the bigger aspects of your life. Relish every moment, and be excellent at every task.
