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 1 I think about myself.I am happy that I am becoming a 2 person. I think my 3 started when I was at Palomar College.At first , I just wanted to get my 4 and be left alone.I thought I was smarter than everyone else , so I hardly ever 5 to anyone in my class.By the end of my first semester , I was really 6 . It seemed as if everyone but me had made friends and was having fun.So I tried a(n) 7 . I started asking people around me how they were doing , and if they were having trouble I 8 to help.That was really a big 9 for me.By the end of the year , I had several new friends , and two of 10 are still my best friends today. A bigger cause of my new 11 , however , came when I took a part ­ time job at Vista Nursing Home.One old lady there who had Alzheimer's disease( 阿尔茨海默病 ) became my 12 . Every time I came into her room , she was so 13 because she thought I was her daughter.Her real daughter never 14 her , so I took her place.She let me 15 that making others feel good made me feel good too.When she died , I was 16 , but I was also very grateful to her. I think I am a much 17 person today than I used to be , and I hope I will not 18 these experiences.They have 19 me to care about other people more than about myself. I 20 who I am today , and I could not say that a few years ago.
