In "House Rules," Jodi Picoult emphasizes the importance of logical thinking in our lives. It serves as a protective mechanism that helps us avoid unnecessary worries and unrealistic hopes, ultimately shielding us from disappointment. By relying on logic, we can make more informed choices and assess situations more realistically.

Conversely, the author highlights the pitfalls of imagination, which can lead us to become overly excited about possibilities that are unlikely to materialize. This anticipation can set us up for disillusionment when our dreams don’t match reality. Picoult advocates for a balanced approach, suggesting that while creativity is valuable, grounding our expectations in logic is critical for emotional well-being.
