If you’ve never seen the movie “A Knights Tale” I recommend that you do. In the movie, the character William played by the late Heath Ledger mentions about the ability of one to change his stars. The movie is set in the olden days (think Knights of the Round Table old) and William made the decision to assume the life of a knight to effectively change his stars. And he did just that. No real spoilers here though, watch the movie to find out how he did it.
