I weigh myself daily and I'm not making excuses for it. Sometimes I go to a weekly routine, but it seems like when I do, my weight goes up. It's like seeing a number on the scale reinforces that what I'm doing is working (or not). I like that feeling and since I do admit I care about my weight and the number I see, I'm not apologizing. I am not anorexic by any means, just trying to stay at the weight which is good for me, which is getting harder to do as the years go on. Since I love eating, cooking, and going out, I have to monitor.
I've had the same scale for 12 years and it still is very accurate.
