1. Figure out what matters.
2. Apply all resources to gather the basics.
3. Eat, sleep, work, play, speak and live them constantly.
4. Expand on the basics, keeping perfection in mind, never allowing yourself to stray afield.
5. Live like you know what you know; be that professional you are sure exists.
This is how to become excellent at anything. Good, bad, wicked, ugly, beautiful, they all use the same formula.
Above everything, remember this:
Every one becomes absolutely perfect at what they do. Most succeed at being worthless. Some come close to excelling. Few continue to drive to excellence.
