I completed my very first project involving home wiring: swapped out the old light box in the ceiling for a new fan-rated box, reinforced the wooden bracing with extra wood screws, then wired and installed a new ceiling fan.
It took a LOT of research, and I had to double and triple check my connections before I proceeded. I'm wary, but it's working.
Luke had never seen a working ceiling fan before and stared at it for a good half hour.
