I have a feeling that being in work and not doing a lot is a large part of it.
I have this problem - my job is very feast-or-famine in terms of there being anything to do. If you spend a day at work and achieve nothing, it somehow saps you of all your drive to do anything at home.
One thing that does work nicely is reverse telecommuting - each morning, e-mail yourself a list of non-work tasks which you can do at work (calling electricians, pricing up kitchens, etc). This is a WIN in several categories a) you look impressively busy b) you go home feeling like you've achieved something, even if there was no work to do c) you've already done half the home tasks you previously lacked the energy to do after work, so you can play Mario Kart.
Alternatively, change job and get out of your comfort zone. If I were a braver man, I'd move job each time I felt I'd hit my comfort zone. I might do it yet, in future.
EDIT: A hard bike ride in the rain while listening to the track You Could Have It So Much Better by Franz Ferdinand works well too. Excercise and rain/wind make you feel alive, and that song just shouts at my apathetic core - "I'm just the voice in your earpiece, telling you no, it's
not alright. You could have it so much better, if you just get up, get up, get up, &c". Good stuff.
