Young women are now totally free to exploit their huge advantage: the youthful bodies that they have. And they do. The tables have turned so much from the olden days that even not so attractive women can play the game rather satisfactorily (at least from their point of view). As such, there seemingly is not much need for self-improvement. They are just awesome as they are.
In reality this is not the case. If women want to be successful in the long term, they can’t depend just on their youth and the sex that it leads to. Obtaining marriage, and furthermore being successful in it, requires more. The path to obtaining more is through self-improvement, which is driven by introspection.
From Wiki: Introspection is the examination of one’s own conscious thoughts and feelings. In psychology, the process of introspection relies exclusively on observation of one’s mental state, while in a spiritual context it may refer to the examination of one’s soul. Introspection is closely related to human self–reflection and is contrasted with external observation.
By considering what you have done, why you did it, what you really are, etc., one can identify areas of improvement. Furthermore, a better understanding of how the world works and how you fit into it should result. Of course, people don’t like looking back at events and situations that did not turn out well. But it has to be done. If nothing else, a dose of humility might be administered; modern young women need that. One might wonder why one has to even suggest that people be introspective. To ask the question is to answer it.
