In my own life, I live in what I would consider comfortable circumstances. We're not rich or anything, but we have a nice house and everyone but me has a car and we don't want for much.
For me *personally* at this time I'd have to say something that affects only me, like buying a lot of scented candles or new clothes or stuff for the computer. After my bills are paid, everything extra is currently going towards my WDW trip in September.
