I used to do the same thing, I'd worry about how much I was getting done in a certain time-frame. It's a typical type-A personality trait to worry about how you're spending your time. I was always trying to maximize the "effectiveness" of my time, or maximize my "fun." Instead I just drove myself crazy putting loads of extra pressure upon myself.

I've gradually put less and less pressure on myself. I've slowed the pace of my life down a whole bunch so I can actually breathe. It's actually helped me more to do that than to spend my entire day trying to improve myself. It's helped me see myself for what I really am, which has given me good insight into what is actually going to make me more content.

My suggestion? Put the clock in a place where you can't see it and take longer lunch breaks.

Edit: My obsession with time also had a lot to do with a deeply-rooted psychological imperative to prove myself to those around me that I wasn't inadequate. Maybe that isn't you, but it certainly was me. It drove most of what I used to do, and I'm glad I finally figured out why I used to push myself so hard. Like I said, now I can breathe.
