My friend Chris is one of the hardest working people you could meet, with two kids, a full-time communications job that she does from home, and several freelance writing jobs that she does...I'm not sure when...probably when the rest of us are sleeping.
And she's creative, to boot. Here's a great idea you can steal from her: She frames her children's artwork and arranges it above her desk. The pictures are easy enough to replace as the kids come up with something new.
The result: a colorful, fun wall that keeps changing and keeps you smiling.
So put your kids (or someone else's) to work. Faster! Faster! Or no supper!
