"The Calling" to me is the Biblical calling that God has to all women, stated in His word in passages like Proverbs 31, Titus 2 and 1 Peter 3.
This is the most noble and true calling of a woman, to take care of her husband, children and do good works in the community in the name of the Lord.
Admittedly this can be difficult for young women in my position who aren't married and must provide for themselves. There is no husband or children to take care of and because the duty of financial provision falls to the young woman, after a long day of work there isn't much gusto to go out into the community and perform good works.
But where there's a will there's a way. If you want to serve God and fulfill your role as a woman, the Lord will provide the means.
