New shoes are wayyyyy better than all of those things.
I get a shiny new toy every five pounds I lose. This is a delightful and appealing carrot. With ten pounds gone, I can replace my tired old Shox with fun Nike Free X-Trainers. Pink ones, at that.
This is the type of carrot that appeals to me. I like shoes. Things like this keep me going. Mani pedis and massages, while they work for some people, are not the sort of incentive that keep me going when I want a cookie and to hit the snooze button through work-out time. They are nice rewards, but they don't motivate me to an extra ten minutes on the treadmill, or swapping salad for fries. I know myself, you know? I know what I want. I like getting what I want.
I like carrots. I really like 15-pound carrots, don't you?
