I have tried to write this diary for my memory every day. But recently I was so exhausted... e.g. Last night I slept at 2am. And at this morning, I woke up at 3:45am. Go to work in the early morning. I finished to work at 22:30. I came home at 23:30. Almost next day. It makes me difficult to continue writing sometime. This life pattern won't be continue, though. I think it's only at this moment. Nowadays, I cannot sing, I cannot do anything else after work or before work as I'm terribly sleepy.
