Maybe I need a theme

Some authors tend to develop one theme across all of their work. 

For example, Madeleine L’Engle’s work makes a statement about *“love versus greed of power seekers and individualization as opposed to regimentation,” and Jacqueline Woodson’s theme seems to be about hope.

Uhm, what could my theme be? Independence? Self-reliance? Education Conquers all? Friendship?

I think I’m in trouble. Will I ever get an idea and stick with it?
