The quote from Jodi Picoult's "My Sister's Keeper" uses the metaphor of a fire to illustrate how difficult situations can escalate if not addressed properly. Just like a fire will extinguish itself without additional fuel, our problems can intensify if we do not seek help or make changes in our lives. The importance of taking proactive measures becomes evident; ignoring issues can lead to overwhelming consequences.

Furthermore, the imagery of flames at one's heels signifies urgent danger. In such moments, one may need to take drastic actions, likened to breaking down walls, to escape from their predicaments. This emphasizes the necessity of resilience and courage in facing life's challenges. Ultimately, the quote conveys a powerful message about empowerment and the need for decisive action in the face of adversity.
