For me, saluki, it's more working on getting a "so what" response/feeling when I bother to look in the mirror. If you don't like what you see looking in the mirror, why do it very much? And so what if you are fat and ugly. Take that to its extremes and you still end up with a life to live, school to attend, job to work, etc. Since it is all perception rather than "real" (no one can say definitively what "beauty" is or why one person appears fat and the next, at the same weight might not, etc.) I'm 125 pounds overweight but no one guesses that because I'm naturally built well. Yes I look overweight but I don't look like I outweigh 98% of the linebackers in the NFL which I do :-) The "looks" part isn't anything that can be controlled, it's deceptive. When I weighed 127 ages 15-25, everyone thought I looked too thin! It was the "right" weight for me because no matter what I ate, I only changed a pound or two in any direction (and I've always eaten; hence my overweight now :-)

Think about what you think and worry about. Much easier than thinking and worrying about "real" things? If we can't do anything about some things, thinking about them and letting them control our thoughts and lives is using up energy we could be using to go after things that would really make us happy. Focus away from the mirror and it is harder to "remember" how fat and ugly you are.
