     I used to watch her from my kitchen window. She seemed so small as she muscled her way through

the crowd of boys on the playground. The school was across the street from our home and I would

often watch the kids as they played during break. I remember the first day I saw her playing basketball.

I watched in wonder as she ran circles around the other kids. She managed to shoot jump shots just

over their heads and into the net. The boys always tried to stop her but no one could. I began to notice

her at other times, basketball in hand, playing alone.

     One day I asked her why she practiced so much. Without a moment of hesitation she said, "I want

to go to college. The only way I can go is to get a scholarship. I am going to play college basketball. I

want to be the best. My daddy told me if the dream is big enough, the facts don't count. "Well, I had to

give it to her-She was determined. I watched her through those junior high years and into high school.

Every week, she led her school team to victory.

     One day in her senior year, I saw her sitting in the grass, head in her arms.I walked across the street

and sat down in the cool grass beside her. Quietly I asked what was wrong. "Oh, nothing," came a soft

reply, "I am just too short." The coach told her that at 5'5" she would probably never get to play for a

top ranked team-much less offered a scholarship. So she should stop dreaming about college. She was

heartbroken and I felt my own throat tighten as I sensed her disappointment. I asked her if she had

talked to her dad about it yet. She told me that her father said those coaches were wrong. They just did

not understand the power of a dream. He told her that if she truly wanted a scholarship and that nothing

could stop her except one thing-her own attitude.

     The next year, as she and her team went to the Northern California Championship game, she was

offered a scholarship and on the college team. She was going to get the college education that she had

dreamed of.
