Its better really to feel good in your current body then to pick on what is wrong with it because that thought keeps it in a state of being wrong, out of balance or sickly what ever the issue you have with it is.
“Do you have to think specific positive thoughts about your body in order for your body to be the way you want it to be? No. But you have to not think the specific negative thoughts. If you could never again think about your body and, instead, just think pleasant thoughts — your body would reclaim its place of Well-being.”
