After this summer vacation starts, I am free every day, every moment. I am really free. But I have to study for my test in my all free time. So I am so bored these days. When I don't want to study, I always use my cell-phone to watch a facebook and talk with my friends in kakao-talk. By the way, I tought I waste my precious time. So I dicided to do something new and worthy.
I started to go to fitness center today. Because I think It's so hard to study for a long time. I have to develop my physical strength. I just arrived at library to do English homework after I finished my exercise. I will exercise hard everyday from today. I feel really great about what I did. I will be healthy.
