I don't even own a scale! I do have a measuring tape though, and I measure myself every Sunday as soon as I get up. I only get to weigh myself when I go to visit my mother, who lives an hour away.
And I agree with you, when I lived with a scale I would be on it all the time, freaking out if I gained a pound, and then I realized that who really cares what the scale says so long as I look and feel good? So that's what I'm really working for... but I still have my little (probably outdated) tracker anyway.
