That's exactly what the Self Esteem Movement got wrong.  They thought that, since self-esteem correlated with accomplishment, giving every student a gold star for nothing would make them perform better.  In reality, students had self-esteem as a result of doing well in sports and academics. That's the crux of the problem with "confidence" talk and body-positive talk.  Confidence, happiness, etc. comes after and is the result of making yourself attractive.  I didn't feel better about myself after a therapist talked to me, I felt better about myself after I grew my hair out and a guy sucked me off in the locker room.  That's why Under_the_bluemoon is delusional.  She's trying to psychologick herself out of a physical problem.
