You are right...low self-esteem often has its core roots in our past. Somewhere along the way, someone criticized us, made us feel less than, and because we didn't know better, we believed it. Unfortunately, we carry these false beliefs with us along our life's journey, unless we proactively work to address them, untangle them, and dissolve them. I like your suggestion to those with low self-esteem to begin celebrating their successes.
