a) I took a ten in math class today.I went to the black board and solved the exercise in a blink of an eye.My mother is very proud of me.
b) My great uncle once told me never to pick a job just for the money, because it will seem a hard work.But if you pick a job that you like, you will never work again, and that means that if you like what you are doing it will never seem a hard work.
