From Rory Miller

Musashi's rules / my commentary:
1) Do not think dishonestly. Do not lie to yourself, ever.
2) The Way is in training. Work and learn hard, no one has ever improved by sitting on their ass and waiting.
3) Become acquainted with every art. Never pass up an opportunity to learn how an artist or skilled craftsman thinks or sees the world. Seek out the best and listen.
4) Know the ways of all professions. The world works because people do jobs. Learn about the jobs that make the world work and how they interconnect. Know ditch diggers and burger slingers, architects and doctors and understand how they need each other.
5) Distinguish between gain and loss in worldly matters. Know what matters. Protect what is truly precious, let go what is not. Do not lie to yourself about these categories or let society lie to you.
6) Develop intuitive judgment and understanding for everything. Trust your gut. Practice trusting your gut. Then practice deciphering your gut so that you can explain it verbally and you will develop intuition AND understanding.
7) Perceive those things that cannot be seen. Everything leaves tracks. Everything affects other things. When you learn to read the tracks, you can deal with invisible problems, like past trauma in a student.
8) Pay attention to trivial things. The tracks are in the small things, and small things affect big things. The tightening around your eyes will tell me more than a hundred of your words.
9) Do nothing that is of no use. My personal favorite- if you spend time doing something, it should make you or the world better. How many hours are wasted each day with TV shows that you won't remember next week or trivia or... how strong would you be if that time was spent working out? How much better could you make the world if the time was spent helping others?
