setting goals ( the right kind)

I am writing this carefully, because I don't want people to take this the wrong way, we all need goals. However with that said. I do have some concerns over some of the goals I see posted . I know what it is like to have a lot of weight to lose so I know the need for goal setting.
Here is the thing. I see on here some people who say they want to loose so many LBS by such an such a time or get to a certain size by whatever date. Some of it is realistic, most of it is not.

What I have learned over the course of time . Is sometimes that can set us up for failure if we don't reach those goals. Especially if the goal is too big. For instance I want to loose 40lbs in 4 months. Maybe, maybe not.

Why not set a goal, like For this month, I'm going to give up white flour and white sugar, I'm going to eat only whole grains.

Or for this month, no potatoes, and no white flour. Just see how good your body feels. Just strive to make good healthy eating choices.

If you work out 3 times a week, make it 4 or 5 times. Dont put your emphasis on those numbers. When you do it gets stressful. I know when I do , I get discouraged when I don't see what I want. The weight will drop, inches will come off, but more importantly you will be making good changes that will last for a lifetime. It's not about an easy fix, it's a lifestyle change.

I quit a weight loss program because they were putting too much focus on the scale and not the lifestyle . That is really what it is all about.
