Of course working out is going to is going to make you feel better. You can see the results as you "make yourself better". Your thinking gets more positive (its already positive b/c you decided to get or stay fit) You can steadily go through the change. With a breast enhancement, its like BOOM, they're there.
Plus a girl with low self esteem could have a boob job, nose job, liposuction etc., but if there is no positive thinking from the get go... her low self esteem still remains even if it got a little boost.
In a way it reminds me of the Jenny Jones "Geek to Sheek" shows, everyone knows that the majority of the people who go on there still have some low self esteem going on.
I like i said Lana has to do what she feels is right, and if its surgery than so be it. There is nothing wrong with attracting guys but no one should feel they need to have surgery to do it.
