It helps to break those to-do lists into smaller bits: rather than organize kitchen-->cleean out 3 drawers or cleean under sink. Many tasks only take 5 or 10 minutes when broken into bits, rather than a 4 hour project. It is motivating to see lots and lots bits crossed off the list rather than the BIG project that doesn't seem to get any attention. This can be applied to all areas.
Also, I like to use the carrot on the stick approach for myself: just complete a, b, c then you can use the computer for 30 minutes.
Having a routine/schedule is also a help in time management.
But I have room to improve, despite the above!
