I'm exhausted...

These days I feel very tired...
Usually I sleep about 5 or 6 hours and that was enough for me.
But now no matter how long I sleep I can't feel refreshed. And also I can wake up on time but I can't feel that I slept enough.
What do you think can make my sleep better...?

Starting a blog

The new semester had started so I was deciding to start something new!
One of the thing I was deciding was blogging. (So that means I've already achieved one of the goal!!)
I would like write many interesting things on my blog and do my best to make my blog fun!
