Welcome Smilyus!

I'm not sure how other people set their minigoals. I tend to set mine in milestones. For instance, my first goal was to get out of the morbidly obese category. The goal I'm working on now is to get below 200.

Since a lot of people tend to lose inches even when the scales aren't reflecting that, and since your ultimate goal is a size 8-10, you might enjoy setting your goals in clothes sizes.
