I want my cast removed as soon as possible!
Why do  you want to remove your cast so soon?
I don't want my arm to look ugly.
While having a cast can be uncomfortable and it's understandable that you want it off as soon as possible, you need to listen to your doctor's instructions and keep it on. If you remove a cast prematurely, you risk permanent disfigurement of your arm as the bone does not set properly. Try to be more patient now with your cast so you don't risk additional medical procedures in the future.
I don't care. I want if off as soon as possible.
I think it's the wisest to just keep your cast on for as long as the doctor tells you. Following doctor's orders are extremely important, and if you take it off early, how do you think they would feel, or how your arm would heal? How about you keep it on, and then reward yourself nicely when your doctor removes it?
