When you think of excellence -  do you think of perfection? I used to think they were about the same thing. Excellence requires commitment. It requires you have a solid idea of where you are wanting to go. It also requires and honest discussion with yourself about what things are holding you back. It is requires keen self awareness and maybe admitting we we may be stuck in a world of things that are not real. Breaking out of that world requires mental and psychological adjustments and learn to regard the adversities, circumstances, and conditions in your life . . . and perhaps a teaser discussion about Plato.
