I work for a company that distributes laboratory equipment- but we all where multiple hats. So in the afternoons I often ship. (Unpacking and packing boxes, shipping etc). I actually really hate shipping- but not because of the physical aspect of it. I just have so many other jobs that need to be done at my desk!
Regardless, when I'm out in the warehouse shipping, I always repeat to myself "Move with a purpose!" It works with house work too. Instead of dragging my feet around and slowly going through the motions of cleaning, etc.. I move with a purpose. And that purposed would be to do it, and get it done!
