I've noticed that most people like to set a ton of goals- weekly goals, monthly, even daily goals. I like setting them because they remind me of what my weight will most likely be if I stay on plan and lose a normal amount of weight (2 pounds a week, usually). It doesn't really keep me on track, or help me lose more, but it makes me smile to see it.
I don't adjust my actions according to my goals, because I just stick to my plan no matter what.
Do you believe that setting goals helps you lose more weight, or does it help you in other ways?
How often do you set goals, and do you tend to overestimate or underestimate?
