In the end it doesn't matter what we all do... so long as YOU find a mini-goal system you like!
I'm doing 5% of my original weight. So... it's 5% of my original weight, then my next goal is 10% of my original weight, and the following is 15% of my original weight. BUT! I'm also adding in other weight goals in between. I have a LOT of mini-goals. I like achieving things... >.>
5% = 311.3 (Made that one)
25 lbs = 302.7
Below 300 = 299.9
10% = 294.9
Oct 2007 weight = 280
15% = 278.5
50 lbs = 277.7
etc, etc.
You get the picture. I have percentage goals, and other personal goals that are important to me. Most of them aren't more than 15 pounds away from each other. Some are as close as a pound or two. And then I'll be thrilled to be "under 290, under 280, under 270" and so forth and so on.
The more mini-goals the merrier to me!
