You should not have a favourite weapon. To become over-familiar with one weapon is as much a fault as not knowing it sufficiently well.
Miyamoto MusashiWhen your opponent is hurrying recklessly, you must act contrarily and keep calm. You must not be influenced by the opponent.
Miyamoto MusashiDo not think dishonestly... Distinguish between gain and loss in worldly matters. Develop intuitive judgement and understanding for everything. Perceive those things which cannot be seen. Pay attention even to trifles. Do nothing which is of no use.
