1. Food. Once a week I eat whatever I want, whatever the cost. Usually adds $30 spent, which isn't really much for me.
2. Travel. Twice a year, or so, I like to go OS. I wouldn't consider cutting this, ever. Flights are expensive, but when I'm at a destination I don't spend much.
3. Quality clothing. I wear it all day every day, I prefer that it fits well, feels good and looks good.
4. Haircuts. I love my hairdresser: he's great, a cool guy, charges reasonable money and makes me feel handsome. I've had ugly haircuts before and just hate how I look and feel when I've got them.
