Can't Sleep But Why ???

I have sleep problem these two three days.

Maybe cause I have a lot of thoughts when i was about to sleep.

I know that I should empty my mind at that time.

But I just can't.

Last night, I slept at 5am (Sydney),

And I'm not going to class this morning.

Too tired to wake up.

I have to correct my sleep cycle again.

So that, I would have enough sleep at the right time.

Time is gold, precious.

If I'm not appreciate it, I would lose.
