- Do not think dishonestly
- Study hard
- Learn every technique
- Learn all you can of other professions
- Distinguish between gain and loss
- Develop intuitive judgement
- Perceive things below the surface
- Pay attention to trifles
- Do nothing which is of no use
-- Miyamoto Musashi, A Book of Five Rings, 1645 AD
