Too many mind. Mind the sword, mind face, mind the people watching. Too many mind The last samurai.
Meaning:Remained focused on what you are doing. Do not worry about what is going on around you. put all your energy into what is now. Do not think about who is watching you, or about those bills you forgot to pay. You have plenty of time to think about that later.
A friend told me that quote before my first kung fu belt testing, and proceeded to tell me not to worry about who is watching, just do it the way I practiced. It helped me relax.
