The things that changes in my life

I've been to ISU for about 2years. I live a pleased life here, and i have already changed a lot after i try another living environment. When i was in my home country, i didn't study very hard and i didn't know the effort that my parents did to support my life. After i came the Ames, i made many friends and learned more things from them. I recognized that i can't live for just myself. I take the hope of my parents. And i learned the word "responsibility", which is the right and limitation in human life. Everyone should suffer the effects that he or she has done before, no matter the good or bad changes for their physical life or abstract mind.
