Hello everyone. I woke up at 7:00 today. I woke up at 7:00 today because I had a part-time job that started at 8:00. I usually start my part-time job at 6:00 a.m., but today I had to go to work later than usual. That's why I woke up at a later time than usual. Whenever I work part-time, I always feel sleepy in the morning, but today I didn't feel sleepy at all. I do club activities at night and eat dinner after I get home, so I sleep late, sometimes for five hours and sometimes not for five hours. Sometimes I can't sleep for five hours, but today I was able to sleep for seven hours. I felt again that sleep is very important. There are many times when I can only sleep for five hours, but I think I can get faster if I spend less time on my smartphone at night. I would like to reduce the amount of time I spend on my smartphone because sleep is more important than anything else. When I touch my smartphone, I lose my attention span. I forgot to turn off the tap after washing the bath yesterday. I forgot to close the tap after washing the bathtub yesterday, and it was because I touched my phone right after. It makes me lose my attention span. I want to rethink the way I use my smart phone for the future.
