Just because "she" has something you don't, doesn't make you LESS or her BETTER - it just means she has it and you don't.  That's all.

I've been witness to the staggering increase of anxiety in teenagers because they are so busy comparing themselves to others.  I've also seen it in my clients.  "Her house is cleaner than mine because she has a cleaning lady." - SO WHAT????

STOP comparing yourself, because YOU are amazing!
