A lot more progress done the past couple of days. We finished the lights in the garage, added more outlets (including a USB outlet by the workbench), and I built a couple of shelves on the side. And for the record, I had a family friend, who is a retired electrician, help me with the lighting and he's been teaching me a lot.
Today, me and my fiance mostly put together furniture. We put together our dining room set and our TV stand. I think next, we have to start really cleaning the garage floor as we'll probably end up epoxying it within the next couple of weeks.
