What is the one luxury you couldn't go without?
Many finance books talk about giving yourself an allowance, so you feel like you have some pampering in life. One of my favorite books went a little farther talking about a specific luxury, which seemed better to me. So long as you had that item or experience you could feel like you weren't "going without" no matter how little spending money you had.
Mine was hair dye. So long as I felt my hair wasn't nappy, I could feel like I wasn't pulling myself out of the drudges and never felt like I was poor.
What's yours?
