Simply stated, the "right reasons" are that you would feel happier for yourself with the changes that can be safely and realistically made given your own body and its starting point and limitations. It usually works better for people who have liked an area before that has now changed. Patients that have "always hated" an area have a harder time ever becoming happy with surgery.
The "wrong reasons" are to have surgery because you desire secondary gains such as keeping a job or getting a new one, saving a failing relationship or starting a new one.
Of course, having surgery if your expectations won't be met is wrong. Also, make sure you are a good healthy candidate for surgery because there is no point in taking unnecessary risks when the surgery is totally elective.
