If you give a mouse a paint brush?

I really want to paint my basement....... but if I paint my basement, I'll want new carpet....... Then I'll want a new rug....... Then I'll want a new couch.......... And new pillows....... And new drapes..... You get the idea. We've been in our house almost 13 years, we've redone almost every room in it, the cycle is starting all over again.
