I was very sleepy today. Yesterday I had a night shift last night. I didn't sleep at all, and so I kept drowsy all day. I almost fell asleep, and I tried not to fall asleep during today's meeting. I made many little mistakes during my work. My work didn't proceed at all. I shout cureses every time I made mistakes. I recognized the importance of sleep. Today, I would go to bed early.
