Another good thing I learned is instead of making the goal something that is prone to the succeed-fail game, is rework the goal so that it is win win; every little bit helps. Focus on general improvment of health. That way, even if you gain some of the wight back, maintatining the focus on your gneral health and global well being will keep you from being totally shot out of the watter if a few pounds come back, and will probably help shed them again. For that, though, you have to really shift that focus for reals.
So don't just excersize for weight-loss, work up your condition or strength, replan your diet so that you get all the food areas in and so you eat better, not just low calorie, and so on. And make sure that you nourish the creative side of your life and your mind as well. If you make one thing the whole goal of your life, you're going to be more likely to fall back into bad habits and sabotage it. If you want real results, strengthen all of you!
