Is it wrong to have a goal in life to be as slim and good looking as possible?

Yes education and other stuff matters, but I can't help feeling I should look better and be easy on the eyes for men by losing weight and looking better. I don't care how old he is, what race or religion if its a guy I feel its my duty as a women to shape up and I feel horrible when I leave outside looking so fat and out there. Isn't this natural anyway as a women?

I feel am a insult at the size I let myself go at.
Its like I woke up or something.
