Limey: I know it helped my mother to set short term goals in order to lose weight. IE: after one month she wanted to be down 5lbs, after 2 months 15, ect ect. Unfortunatly chips and salsa has done her in. (plus she was on the atkins...can be dangerous diet). Since the weight i need to lose is not very much I don't feel the need for the short term goals.
