Personal - Work

I couldn't concentrate on work while I was at the office, and now that's all I'm thinking about. I bet I'll dream about my algorithms. Why can't it be like this when I'm at my desk, where it's useful? Oh, it useful now too, sure - I'll get more done tomorrow after thinking about it today, but it's not the same: can't keep it all in my head. And I can't take my work home, even if I could afford a laptop. Wah.
