Smoke Detectors.

They get me off of the computer and the recliner and lead me to the final goal of being able to spend more time with my family (and my wife doesn't mind me doing all the work I am accomplishing as well :) ).Last month's goals were to paint a room and cover, install and wire into the electrical system smoke alarms, tar paper and shingle the patio.
