Revising or rethinking / reworking

Revising or rethinking / reworking is necessary for people to improving ourselves or make something better, also in my opinion, to check on the past value that we had, or our experience, will be kind of revising or rethinking / reworking too, because this action makes our behavior or works much further better. Revising or rethinking / reworking is important for my life. Especially, it is important for my campus life. I have been living in America since July, and I have had a lot of language mistakes and culture difference, because I am international student, but each time revising and rethinking have helped me a lot to improve my English. Also revising or rethinking / reworking is necessary to improve my piano performance.

My campus life past over a month, and I still don’t understand what the faculty members are speaking in class, also I do not understand what students are talking in class or with their friends. Especially, writing assignment is very hard to me. I always have some grammar errors, and using wrong words for the sentence, so I try to revise and rethink two or three times each assignment. When I revise some thing  always try to be other person, because when I’ve finished the assignment, that assignment is perfect to me. After finished revising, I still have a lot of mistakes, but this action makes my English skills better. 

I chose music as a minor in this university, and I sometimes practice some pieces, I usually record my best one each day, then listen to the performance and write down where I had mistakes and where I should change or revise, and try to fix mistakes and improve my performance totally. Recording is useful to revise and rethink my performance, because I can listen to my performance objectively.

Therefore, revising or rethinking / reworking is important to improve my English and piano performance.
