One of the biggest problems I see in the bariatric community - with each of us individually - is how we let other people's successes affect the joy we get from our own successes. If someone loses 5 more pounds than me, should I be resentful of that person's success? No, of course not! But how often do we hear newbies compare themselves to others who are the same time out from surgery who may have lost more than they did. All the time! "So and So lost 50 pounds already, why have I only lost 40 pounds?"
Don't do that! Don't allow yourself to diminish the amazing work you've done by comparing. Just don't do it.
