I think that it is definatley a good sign that this starts on your birthday. It will help you to remember when you started to change into the person that you want to be. Deep down inside you know that you have all the mental grit and determination to make this happen. stay focussed on the small goals and the larger ones will come easier. Concentrate on the next two pounds rather than the 48lbs.
By the yard it's hard! By the inch it's a synch!
Keep going. I believe in you.
