Mini-Goals are an absolute must for me too. I usually do not associate a specific date with them. They are more like everyone else has mentioned - just targets I won't to meet and I celebrate them by treating myself to something nice - NOT FOOD!!!
Mini-Goas for me:
10 pounds
25 pounds
ONEDERLAND
40 pounds
50 pounds - Just hit this one as of today and I will be getting a manicure and a pedicure one evening next week in celebration!
It really helps to motivate me to always know I have an attainable goal in front of me.
