I have a lot of mini goals, they are more fun to focus on IMO. When I first started at 195 lbs, I set my mini goal at 10% body weight, which brought me to about 175. Then I made a goal to get into the 160's, now my goal is to solidly be in the 150's. And so on.
I also have clothes goals, for example at first I wanted to fit into a pair of capri's that were skin tight. Done. Now I have a few shirts that are a bit too tight but would look great in 5-10 pounds.
Another goal is lowering monthly binges. I just figured out that I had 11 (!!!!) binge nights in August. My goal for Sept is to have a lower amount than that.
All that said, I still think about my FINAL goal weight a lot. It's a weight I've been at most of my life, so I know exactly what it looks like on me and what size clothes I'll be in. But geez, at first it was sooo overwhelming to have 70 pounds to lose that it was depressing thinking of the main goal. The closer I get the more I think about it. I'm halfway there, so I keep reminding myself to take what I did already, and just.... do it again! lol
If you have a long way to go I'd say focus on small goals. It makes you feel better about whole process and appreciate the hard work you are doing.
