Tired

I feel a little tired in the new term, because I need to do more homework and wake up earlier than last term.

Sometimes I can not pay my attention in the class when I feel tired. I sit in the library now and finished my honework here. In the library I can pay attention to do the homework, because of the environment of studing. If in my home I always surf in the internet during I do my homework, so it will waste my time.

I feel a little tired today...
