When I built our entertainment center and matching bookcase, it took me about 9 months each. I was working for that big computer company with the stripped logo 50 - 60 hours per week, so it didn't strike me then that was a long time.
Side story. These two items were built in my 12'x12' basement shop. At some point, after doing a dry fit of the first one in the shop, it occurred to my feeble brain that I had never considered moving the finished object upstairs. I went to a local appliance store and begged a couple of refrigerator cartons. I used them to build a cardboard and hot melt glue mock up of the assembled unit in the shop. Sure enough, there was absolutely no way of getting the thing up the basement steps and into the family room. That would have been rather embarrassing to say the least. The units were assembled and finished in the garage like kits.

I've gone out to find myself. If I return before I get back, have me wait for me.
