I lost my sight when I was four years old by falling off a box car and landing on my head. Now I am thirty two. I can 1 remember the brightness of sunshine and what color red is. It would be wonderful to see again, but a 2 can do strange things to people. It 3 to me the other day that I might not have come to 4 life as I do if I hadn't been blind. I believe in life now. I am not so sure that I would have believed in it so deeply, otherwise. I don't mean that I would prefer to go without my eyes. I simply mean that the 5 of them made me appreciate more 6 I had left.
Life, I believe, asks a continuous series of 7 to reality. The more readily a person is able to make these adjustments, the more meaningful his own private world becomes. The adjustment is never easy. But I was lucky. My parents and my teachers saw something in me—a 8to live, you might call it—which I didn't see, and they made me want to fight it out with 9.
The hardest lesson I had to learn was to believe in myself. If I hadn't been able to do that, I would have 10 and become a chair rocker on the front porch for the rest of my life. When I say 11 in myself I am not talking about simply the kind of self-confidence that helps me down an unfamiliar staircase alone. I mean something bigger than that: an assurance that I am, 12 imperfections, a real, positive person; that somewhere in the complex pattern of people there is a special place where I can make myself fit.
It took me years to discover and strengthen this assurance. It had to start with the most 13 things. Once a man gave me an indoor baseball. I thought he was 14 me and I was 15. "I can't use this." I said. "Take it with you," he urged me, "and roll it around." The words 16 in my head. "Roll it around! "By rolling the ball I could hear where it went. This gave me an idea how to achieve a goal I had thought 17: playing baseball. At Philadelphia's Overbrook School for the Blind I 18 a successful game of baseball, which we called it ground ball.
All my life I have set ahead of me a series of 19 and then tried to reach them, one at a time. I had to learn my limitations. It was no good trying for something that I knew at the start was absolutely 20 because that only invited bitterness of failure. I would fail sometimes anyway but on the average I made progress.
