Writers- If you character had a theme song, what would it be?

My heroine is on a journey back to her birthplace and homeland. She is smart, beautiful and sophisticated but along the way through her life she has lost the plot a little. She found herself in the city doing a job that doesn't suite her. She has some big obstacles to overcome such as how to provide for her family in the country where there is less work. She needs to prove that there are opportunities through the Internet & so I choose 'On a mission' by Gabrielle Cilmi. The words are particularly inspiring - I'll never give up... I will do whatever it takes.
