Ignore the scale ?

Do we ignore the scale when it delivers bad news. Sounds like shooting the messenger. There has always been conventional wisdom that we should weigh in once a week so we do not go on an emotional roller coaster. Today I can see the wisdom in that idea. Even though I was almost a saint the scale treated me like the devil. So I would suggest if we know that we have done well ( via our grades ) it is time to put the scale aside for a few days.
