It's counter-intuitive, but from experience it is the exact thing you will be told to do if you go into therapy.

If you can be happy with yourself overweight then you are not losing weight to be "good enough". If you are losing weight because you are unacceptable as you are then you're putting yourself under a shit ton of pressure and you're consigning yourself to unhappiness until a goal is reached. The pressure and misery you put yourself under makes it more likely you will cave in and comfort eat - especially if you slip up at any point. All in all, you've wasted God knows how long being utterly miserable just because you're carrying a few pounds.

On the other hand, you could say: I'm a bit overweight and I'd prefer to be slimmer but I'm still a worthwhile person and I know I can change the weight. So then instead of changing your weight to be "good enough", you are changing your weight because you really care about your health and you really want to live a healthy lifestyle. It, in fact, becomes less about weight and appearance, because it becomes more about feeling good. You begin to eat well and hit the gym because you really care about your body, rather than because you really hate your body.

I know it sounds counter-intuitive, but it does work. A friend of mine had binge-eating disorder and the first thing she was told by her therapist was to learn to like herself just as she is. Instead of losing in order to be "good enough", she should lose because she cares about her health - because she's important and her health matters. The pressure was off and she lost the weight. That was years ago, she's been slim ever since after years of struggling, and she's happier too.
