I never understood the whole using food to celebrate thing. Growing up the only time I got food as a celebratory thing was birthdays, the last day of school and ice cream after shots at the doctor's office (which was really only a thing until I was like 12). I can't imagine how much I'd be eating if I got myself a doughnut (lets be real they probably get three) every time I did something positive or productive. The treat, in my mind, is the simple satisfaction of getting something done.
