If you train long enough you will experience being the dog and being the hydrant. Its inevitable. One day you can do nothing wrong. Every position, transition, submission comes effortlessly. You are in the zone, on fire, on top of the podium.
Then, on another day you get your ass kicked. Repeatedly.
Being at your best and worst are the yin and yang of training and competition. One cannot exist without the other. Celebrate this fact.
What is important is your response to each of these situations. How you handle yourself during the highs and lows of your performance defines who you are. As long as you train and compete in Brazilian Jiu Jitsu, you will have no choice but to deal with both of these scenarios.
The best response in any situation: Win with Humility; Lose with Grace.
