I always go with little goals. Sometimes I make a list of things I need to do around the house (if I've gotten way behind). I find it satisfying to cross things off.

Also. I bribe myself with small rewards (eg. Ok, you have to vacuum and change the kitty litter. Once that's done...you can watch something.) If I still end up not doing something one day... it's the goal for the next day. Usually I don't miss more than two days in a row before I manage to get my act in gear!

I tend to play music fairly loudly when I'm doing chores. I usually bop around while I clean, even if I'm depressed. I enjoy it once I get started - although I might take ages to eventually get started!
