Voice is a more significant concern because it affects the way you communicate with other people. It is more likely to cause you to feel isolated and cut off, than bad hair or skin.

Changing superficial things, as you put it, is not the entire solution. It is a beginning. If you can do something simple that starts to make you feel better immediately it is easier to take another step forward. Getting your hair worked on or getting a massage is nice. I've even had my nails done, when I saw my wife doing it and it seemed to make her feel good. We both went in together after we had our hair done. Then we went for dinner. It feels good to go out and have someone take care of you for a while. It is a start.

It isn't easy to change the way you see yourself directly. Making minor changes can give you a sense of being in control and taking power. And the advice was given for the purpose of being helpful. You do see that, don't you?
