I haven't played tennis these 5 weeks because I go to a library or prep school every weekend. But I realize that without playing tennis, I can't concentrate on studying well. Also, the lower back or the knees are starting to pain as if they want to do some exercise.
Although I take part in a yoga lesson almost every week, it is not enough for my body. Actually, after playing tennis, I felt refreshed. And I can concentrate on studying, maybe.
Tomorrow is Monday. That means another stressful week starts soon. But I'll manage to do that, because I played tennis today.
