I often become discouraged, and as such I do not allow my goals to set me up to fail. I have a small weight loss goal for the month, usually the absolute smallest amount I could lose under my current regimen. Then I leave the scale alone! At the end of the month I get to see my progress, and I have not been let down yet.
The best part about doing this: I never feel discourage by the number on the scale AND I do not stress about it. Weighing myself weekly was too much as it can fluctuate so much.
