I also, agree you learn frpm practice, not drugs. My tai chi sifu says you must do a movement 10,000 times before you know it, ie practice makes perfect or at least makes you able to do things reliable.
By that 10,000th repetition, not only have you dug a nice, deep mental groove but you have all those ‘muscle memory’ things in place and … let’s face it… you no longer have to THINK about the move — the move ‘happens’.
A good martial artist does not become tense, but ready. Not thinking, yet not dreaming. Ready for whatever may come. When the opponent expands, I contract; and when he contracts, I expand. And when there is an opportunity, “I” do not hit, “it” hits all by itself.
