Never be the end of the line, lest you leave yourself nowhere to turn. If you think "I'm the one that everyone else turns to for help," then you need a contingency plan, a backup plan for yourself. No one is unbreakable, that is absolute and not a sign of failure or weakness. One day every hero will need her own hero, and if she hasn't thought about it and made a plan in advance, then things will not turn out well.Do you know who you would turn to when things go bad?Can't wait for the dramatic conclusion.
