My Daily Life

I have a regular daily routine. On weekdays, I always get up at 6:30 a.m. and then go to school by bus. I have four classes in the morning and three in the afternoon. After school, I usually go home and do my homework first. In the evening, I often read books for about an hour. I sometimes watch TV, but I hardly ever play computer games because I want to protect my eyes. I go to bed at 10 p.m. I think my life is busy but healthy.
