A Good Night

I went to bed too late last night, so my energy not well today, and I can`t concentrate on my work well. People told us that the whole day`s work depends on a good start in the morning. I don't think so. I agree with another said: The whole day`s work depends on last night. If you have a good preparedness at last night, generally speaking, you have a good state in the next day. Of course, a strong man who is full of energy don't need to worry about this, because he can keep his energy well after have a short rest. But for me, it's difficult. So I decided to write essay early today in order to have a good night.
