From The Book of Five Rings by Miyamoto Musashi

1. Think of what is right and true.
2. Practice and cultivate the science.
3. Become aquainted with the arts.
4. Know the principles of the crafts.
5. Understand the harm and benefit in everything.
6. Learn to see everything accurately.
7. Become aware of what is not obvious.
8. Be careful even in small matters.
9. Do not do anything useless.

When you take into account that Musashi was speaking of science, arts, and crafts in general, not only in relation to combat, these rules can easily be applied to all things in our daily lives, including noding (see rules 5,6,7, and 9 in particular).
