i have similar goals, mostly with house work though.
have you every heard of fly lady? it's a book that sounds silly, but it really helped me by learning to set rediculously small goals that add up throughout the day. i don't follow the book by heart, but i do still incorporate some of the practices.
the book is called "Sink Reflections"
and she has a web site: http://www.flylady.net/
it's amazing how some of the simple steps in the book make such a big difference in how you feel.
