I'm sure we have all been there. How about this time, as you get stuff out of your closet you don't punish yourself with what you didn't do and decide to bless someone else with your carefully stored clothes that don't fit ... yet.
If you have a few pieces that you really love or that you bought as an incentive to lose weight last year ... keep them in your closet and plan to pull them out mid-summer ... after you have finally gotten rid of the weight you WILL get rid of this time. It will be a great reward for you!
Remember: your intention should NOT be to LOSE weight but to get rid of it for good! If you merely lose it, you might just find it again!
