One of my favorite short stories …
Johnny did not see the need to practice hard; he was very bright and always understood quickly. He read the Classics so that he could sound as eloquent as his teacher.
Wanting to be knowing in all things, Johnny read a history book or two and was able to converse brilliantly about history. Johnny read an economics book or two and was able to speak knowingly about economics. Johnny read a few books about swimming……and Johnny drowned.
You can watch videos…..but the reality is you need to learn how to execute the techniques in class and then practice outside of the dojo in order to improve.
