you are a funny man, I needed that right then, I had a bad day!
I do recognize the quote, but I like this one -
"One rarely rises to the demands of the situation, one merely reacts with what training they have." (or something to that effect) Paul Castle
"If you don't train to react while getting your ass kicked you'll never be able to revert to training you don't have!" Pierre Auge (this ones mine)
or I just came up with this one
"If you can't hack it don't pack it!" Pierre Auge
