Because there are smart women out there who are more concerned with what is in a man's heart than what is on the outside? Plus, some men who aren't attractive in the traditional sense, can actually be very sexy because of their attitude and masculinity.
A strong woman takes advantage of help she can get from people around her but she doesn't rely on them for anything
She uses logic and manages her emotions
She offers help either because it is a business transaction or out of kindness. It is never because she hopes others will return the favour or out of fear of losing them
She has her own mind and thinks for herself and knows that she has to be the one who bears the consequences of her decisions
