Do you think there is a moral to this story
I think is easier for a woman to fulfill her dreams today becuase back then women wouldn't allow to work in business places, but work as slaves for nursing. Now women can go to work at a business place.
In answer to your first question, I think that it is all dependent on the character of the person. If you are referring to Shakespeare's thoughts, then yes, he would have believed that force of character goes a long way in changing the course of one's life. Look at Romeo and Juliet. The force of their love and, additionally, their headstrong foolishness definitely changed the course of their lives. Without such strong character, doubtlessly they would have been too weak to attempt such fatal actions.
Now, in answer to your second question, I think it is far easier for a young, married woman to fulfill her dreams today, especially when compared to Shakespeare's time. I suppose in order to answer this question more fully, I would need a better reference of which work of literature or time period we are referring to. However, modern society is much more accepting of women in the workplace and women having their independence than many societies of long ago.
