How Do You Motivate Yourself When You Don't Feel Like Doing Household Chores?

I often feel like I would prefer to watch TV or use the PC, but housework has to be done. How do you motivate yourself to keep going at it?

Suggestion:

I like to do my housework first thing in the morning. That way, I can tell myself that I will have the rest of the day to do things like TV or the PC or whatever (assuming I have the day to myself). It gives me incentive to get everything done. Putting on some good music helps as well as I'm doing the housework. I got myself into a good routine doing this, I got to the point of being able to do the majority of things by about 9.30 am (excepting ongoing things like laundry, lunch dishes).

Things are a bit different now I have a son to get to school, but on holidays/weekends then I try to get everything done in the morning.
