                                                     How I Turned to Be Optimistic

       I began to grow up that winter night when my parents and I were returning from my aunt's house,

and my mother said that we might soon be leaving for America. We were on the bus then. I was crying,

and some people on the bus were turning around to look at me. I remember that I could not bear the

thought of never hearing again the radio program for school children to which I listened every morning.  

      I do not remember myself crying for this reason again. In fact, I think I cried very little when I was

saying goodbye to my friends and relatives. When we were leaving I thought about all the places I was

going to see - the strange and magical places I had known only from books and pictures. The country I

was leaving never to come back was hardly in my head then.  

       The four years that followed taught me the importance of optimism, but the idea did not come to me

at once. For the first two years in New York I was really lost-having to study in three schools as a result

of family moves. I did not quite know what I was or what I should be. Mother remarried, and things

became even more complex for me. Some time passed before my stepfather and I got used to each

other. I was often sad, and saw no end to "the hard times."

        My responsibilities in the family increased a lot since I knew English better than everyone else at

home. I wrote letters, filled out forms, translated at interviews with Immigration officers, took my

grandparents to the doctor and translated there, and even discussed telephone bills with company

representatives.  

         From my experiences I have learned one important rule: Almost all common troubles eventually go

away! Something good is certain to happen in the end when you do not give up, and just wait a little! I

believe that my life will turn out all right, even though it will not be that easy.
