I've given myself a few rewards along the way. I think it helped me keep going sometimes. I wrote my weight loss goals and rewards in my diary and each time I reached a goal I got the reward. So over about 8 weeks I got new shoes, shirt, swimmers, mini facial, and a shopping day by myself (no kids). My next reward is when I am 65kgs and that will be a massage, can't wait for that.
The rewards don't have to be expensive (I mainly shop for clothes in Big W, sometimes Target). No point spending too much on clothes when you are shrinking in size hey.
