You're in the mood to shop, big time, and to buy whatever it is you're absolutely sure no one else has -- or, at the very least, no one you know. Before you whip out that plastic, though, think about this one thing: If you really want to be different, why not put your credit cards and your checkbook away and redo something you own -- in your very own way. Invest in some paint and a couple of stencils. You might end up with a profitable part-time business.
