As a stay-at-home mom to two kids under 3, I find that I my daily mantra tends to be "Serenity Now!" a la Seinfeld. The moment one mess or project gets cleaned up, we're onto the next disaster.
This poster from the site Keep Calm and Carry On seems to sum up that sentiment well enough, and will soon hang on the wall of my bedroom.
I'm rather freaked out about putting holes in my walls lest we decide that we're suddenly moving (moving where, I don't know) and have to hire someone to repaint and fix the blemish(es). Now that it's enroute and I've paid int'l shipping, I suppose that I'll have to quickly get over that fear and start enjoying my house...and art.
