Con: I have a tendency to overbook myself, or jump into something without really knowing what I'm getting into. I've gotten better at this with time, but I still end up getting really busy/overwhelmed on occasion.
Pro: Thanks to my extended bachelorhood, I'm very self-sufficient. I cook. I do my own laundry. I don't mind doing the weekly grocery shopping. I know what a duvet is, and how to get one inside it's cover without too much trouble.
Con: I randomly come home with large unplanned purchases: a nail gun, a memory foam mattress, an industrial-grade blender. I will (quite honestly) insist that these are necessary household items. Also, I know what a duvet is.
Pro: I've got a good career at a good company. My job is interesting and challenging. I don't have to bring work home with me.
Con: I'm not a Type-A, live-to-work kind of guy. That doesn't mean that I'm lazy or that I'm not trying to improve myself. I'm just passionate about, and find fulfillment in, other pursuits.
