Notice I didn't say no one could beat her, I am just saying the reason someone beats a world champion is very, very seldom because they know some techniques she’s never seen before. At beginning levels, a player might win from knowing a technique the opponent doesn’t know. At national and international competition, winning comes from knowing the technique better, and that comes from training for years on end. The "want-to" comes on long before the day of the actual fight.
“Today you are You, that is truer than true. There is no one alive who is Youer than You.”
- Practice it every day. In the U.S., it is usual that serious players will have at most one or two teammates who are equally dedicated and the rest of the club will be there just for exercise and a good time. When you are the only competitive player at practice, take some time to go through your entire repertoire of matwork and standing techniques. A weakness of most players is that the number of moves they can do to win are limited. Don’t be most people.
- Make sure that everything fits together. If you usually do a drop shoulder throw, have a matwork move from when you miss and the opponent is on your back. Have another matwork move for when it scores for less than a full point and the opponent is on her side in front of you. Have a throw that sets up to that drop seoi nage.
