Web Design Motivation

I really want to work on my personal site. I also really want to work on a design for this blog, I just can't seem to keep motivated to work on pages at home ever since it started being my full-time job. It is really hard because I can't sit at my desk at home too long because for some reason that makes my knee hurt much more than sitting at my desk at work. Typing on my laptop gets tedious after a while and I lean forward to do that so that also hurts my knee. Add on top of that that I can't seem to load the configuration control panel for my website, and it makes it much harder to want to work on stuff. I am going to start trying though.
