◆Viewpoints&Discussion
1.How many hours of sleep do you usually have? Do you think it’s enough for you or not?
My sleeping time is about 6 hours every day, I go to bed around 12:30pm and I get up around 6:30am. I thought that 6 hours was not short because my sleep was very deep. I never wake up in the middle of my night.
However, recently, I have read one book about sleep. It said that it is necessary to sleep 7 hours to increase good memory. I have thought that this has been my reason that I was not able to remember English. I have to sleep to speak English well.
2.Which is better to be successful, having enough sleep, or “no sleep” at all?
Of course, I think that  being successful is necessary to have enough sleep. It leads us to being beautiful, youthful and healthy. Having enough sleep also can give us good concentration and better memory. Those are very important way to be successful.
3. What should you do if you want to have enough sleep?
This is very difficult question. I have a lot of things that I want to do. I don't think that I make time to have more sleep. I want to work, study and love. If I want to have enough sleep, I think that I have to give up those.
