I don't have to take PE class since this semester. Having PE class motivates me to exercise or to play some sports. Because if there is no PE class, I will not do exercise or playing some sports forwardly. I am too lazy to do those things even though it’s good for me, but I would rather surf the Internet, go out with friends, listen to music, talking on the phone… and so on. I know this is kind of waste of time if I spend too much time on doing these things. I will try to do the things that are good for me even though I am too lazy to do them.
