I've made an observation over the years...

A woman's handwriting can tell you a lot about her personality and demeanor during her formative years, which will have lasting effects later in life:

Nice "girly" handwriting indicates when she was growing up she was a pleaser, pleasant, and was diligent in her studies as evidenced by the very fact she tried hard enough to make her handwriting look nice.

Conversely, I've also observed women who have "manly" handwriting tend to demonstrate more masculine traits in general than their feminine handwriting peers. This possibly is the result of being tomboyish and/or having to fit in with older brothers, which can have lasting effects later in life as well.

This is just one hint, a correlation, at personality & upbringing you can use to screen women with. A tool to put in the toolbox to be used later.
