I used to be a very self-centered person, but in the past two years I have really changed. I have started to think about other people         I think about myself. I am happy that I am becoming a        person.
I think my         started when I was at Palomar College. At first, I just wanted to get my        and be left alone. I thought I was smarter than everyone else, so I hardly ever          to anyone in my classes. By the end of my first semester, I was really         . It seemed as if everyone but me had made friends and was having fun. So tried a(n)       . I started asking people around me how they were doing, and if they were having trouble I       to help. That was really a big         for me. By the end of the year, I had several new friends, and two of         are still my best friends today. 
A bigger cause of my new         , however, came when I took a part-time job at a Vista Nursing Home. One old lady there who had Alzheimer’s disease became my          . Every time I came into her room, she was so      because she thought I was her daughter. Her real daughter never         her, so I took her place. She let me       that making others feel good made me feel good, too, when she died, I was        , but I was very grateful to her.
I think I am a much         person today than I used to be, and I hope I will not         these experiences. They have          me to care about other people more than about myself. I         who I am today, and I could not say that a few years ago.
