next morning I was too nervous to eat my breakfast.
This meet would decide who was going to the Nationals.
Better not to think about Angela at all, I told myself,
recalling Coach's Words. Better to concentrate on my ownrace.
Carefully, I went over Coach's instructions in my
mind.
At the gun, I cut into the top of the water smoothly. I swam
exactly as I had been imagining it before the race, acting
out the pictures in my mind. When I finished, I was certain
I had done my best. Then I heard my name. I also heard
Angela's name, but it was several minutes before I realised
that my name had been called last. That meant my time had
been better. I saw Angela sitting with her back against the wall alone. It could be me, I
whispered to myself, remembering what it feels like to lose a race.
I do this all the time,she burst out. i do great at workouts then comes a
meet,and something happens: i just can't do it. maybe you don't know how to play the confidence game,
I said. She looked
at me, but I went on.
how do you psych yourself up for a race ? i don't exactly. i just try to block it out, not think about it.
What about during a race?
I concentrate on not making mistakes.
very negative methods, I commented
What do you mean?
Well, take my positive approach. First, I think about all the good things
I've done in previous races. Then I plan my race carefully, going Over each
detail in my mind, picturing myself the perfect swimmer. Then when I'm in
the water, I tell myself to do it again, only this time for real.
And you
win, Angela added with a smile. Listen, I have an idea, I said. Maybe I
could make it up to her. You swim faster than me, right? ? Angela looked
doubtful.
Yes, you do, that's an objective fact, I insisted. Now my idea is that you
follow me in the final this afternoon.
At first Angela wasn't sure, but I Soon convinced her, and we were planning
our strategy when Coach showed up. What's going on here? He gave me
an accusing look. We've got it all settled, Angela spoke up. Toby and I
are going to be a team from now on.
All right! he said, giving us a smile.
At the sound of the gun I was into the water. I concentrated on a single
word. Win! Please, please let me be the winner, I whispered over and over
Finally, the winning times flashed on. Angela had won. I managed to give
her a congratulatory hug.
You did it, girls? Coach couldn't keep himself from shouting, he was so
excited. you've just raced yourself to the Nationals!
Well, at least Angela has, I said, struggling to smile.
Coach looked startled.And you did too toby. what was he
talking about? i saw that Angela won the place on our relay
team.
That's right, but you missed something. You both swam so fast that you
made qualifying times for the individual event! So you'll both go to the nationals
