When Was A Time You Were Disappointed In Yourself? A Tennis Disappointment Experience

I climbed in the car, tears filled my eyes. I wanted to slap myself. Why did I lose?! I looked back into the windows of the main building, the boy who had won against me was celebrating. I was soooo mad. I start finding ways to win the next tennis tournament. What did I do wrong? I go over the match in my brain. Telling myself which strategy I should have used.  I go over the correct technique in my brain. A surge of confidence fills my body. The tears are replaced with determination. I will win next time, I WILL!
