Do you have a clothes goal? As soon as I make it into a new pants size, I run out and buy some jeans the next size down and (I'm not kidding here) hang them on the wall in my room. Jeans are unforgiving (unless you buy stretchy jeans), so for me that's the real test of where I am. Every now and then, I take them down and try them on to see how it's going. Until they fit (buttoned and zipped comfortably, I can put my hands in my pockets, I don't get red marks on my belly from them), I keep at it. Then the process starts all over. Even better, I keep at least one pair of old pants once I've lost my way out of them (I donate the rest to the Mission as soon as they're even a little baggy.) And every now and then, I line them all up on the bed and look. It's amazing. To see a pair of size 8 jeans that fit me laying on top of a size 24 that used to is the most beautiful thing I've ever seen (other than my two daughters).
Scales are only numbers and fluctuate frequently even over the course of the day (for obvious reasons.) Find your gratification somewhere else, or learn to see the "big picture" of those numbers, or you will be frequently disappointed.
