I lost my sight when 1 was 4 years old in an accident．Now I'm 32．

It occurred to me the other day that I might not have come to love    36   so much, as I do now, if I hadn't been    37  ．I don't mean that l would prefer to go with no sight．I simply mean that the   38   of it made me  39  more what I had left．

Life，I believe，   40   a continuous series of adjustments to reality．The more   41    a person is able to make these adjustments，the more    42    his life becomes．The adjustment is never easy．I had to   43   in myself，or else 1 would have collapsed（崩溃）．When I say belief in myself，I am not talking about simply the kind of    44    that helps me down an unfamiliar staircase alone．But I    45     something bigger than that：an assurance that I am，despite imperfections，a real，    46     person．

It took me years to discover and    47    this assurance．Once a man gave me an indoor baseball．I thought he was making fun of me and I was   48    ．“I can't use this，”I said “Take it with you，”he urged me，“and roll it around.” The word stuck in my head．By   49   the ball I could hear where it went．This gave me an idea how to    50   a goal I had thought impossible：playing baseball．At Philadelphia School for the Blind I invented a successful  51 of baseball. We call it Ground Ball.

All my life I have set ahead of me a series of    52    and then tried to reach them, one at a time．But I had to be aware of my   53    ．It was no good to try for something that I knew at the start was out of   54   because that only invited the bitterness of   55   ．I would fail sometimes anyway but on the average I made progress．
