You should be a missile and go and destroy your opponent.
The best way to get a move to work is to make it so uncomfortable that the opponent gives it to you to stop the pain.
There is no reward without sacrifice.
Punch a black belt in the face, he becomes a brown belt. Punch him again, purple.
If your opponent is tapping, your technique is good. If he is not tapping, your technique sucks.
Life is yours, do not let life's problems have other influences on what you believe. See for yourself.
