Hahahaha good question!!!!
For starters, I'd have the back room cleared out and useable.
I'd have all my photos categorised, labelled and filed. ALL.
House would be spotless. Probably.
I would have more books downloaded to my brain.
But then again, maybe not.
True Procrasinators have a way of, well, procrasinating regardless and I'd probably have found another forum to haunt and would be back in the same boat.
