weak end

Usually, I look forward to the weekend. Today, however, is different. I feel weak, exhausted from work. Maybe it's too much, I don't know? The most frustrating thing is that no matter how much I try to organize myself and give myself that extra push, I am always behind deadlines at work. I can't understand it. Did something go wrong with my calculation on life? It's not much different this week. Working (as smartly as a I could) for 10-12 hours per day doesn't seem to pay off. Suddenly, there is no week end to look forward. Oh, beer gone art thou again this week...
