7. Maintain your supplies.
Don't run out every other day for paper, printer cartridges and other supplies -- consider delivery. (I use Staples
for all my supplies; their prices are very competitive. They also offer free next-day home delivery -- you cannot beat that!) Keep a running list as you use things up and re-order all at once.
8. Don't get fancy. You don't have to have an elaborate set-up to be efficient and productive. You need to be practical and make the most out of what you have. When I divorced and moved into a much smaller house, I had to reevaluate my office space and went from a large home office to an area on my back porch (it was that or a corner of my bedroom). Neither of these were practical or realistic, so I moved it all to a corner of my living room. I had to adjust my work hours to accommodate my children's schedule and I am now forced to keep it neat and organized (which is a plus). It is not ideal, but I am making what I have work -- and so can you.
No matter what your circumstances, if you decide on working at home, you can be professional and that is half the battle!
