few hours of sleep

It is almost eleven o’clock right now and I am still here on my computer. I thought I could go to bed and sleep before ten but it is passed ten already. I do not know how to budget my time and go to bed early. Every night I only have five to six hours sleep. Sometimes only four and I do not know what to do. I have only a few hours of sleep. I wish I could sleep more but I do not enough time. I have to get up so early to go to work and go to bed late all the time. That is why when I am at work I am always tired and sleepy. I wish I could afford to not need to work but I guess I am lucky that I have a job.
