What do you learn about curleys wife life before she met Curley?

Curley's wife aspired to me an actress, and she seems to think she could have done well in the field. However, she suspects her mother had tried to keep her from the limelight, having thrown away the correspondence inviting her to Hollywood.

What is important, though, is not that she was actually talented. The important part to note is that she COULDN'T have been successful because "the best laid plans of mice and men often go awry."
