"Whenever I was upset by something in the papers, Jack always told me to be more tolerant, like a horse flicking away flies in the summer"

In this quote, Jackie Kennedy assesses the recommendations provided to her by her hubby, Jack Kennedy, who later ended up being President John F. Kennedy. The metaphor of a horse flicking away flies in the summer season acts as a vivid and engaging illustration of how to deal with stress, criticism, or negativeness, particularly that which comes from external sources such as the media.

Jackie's mention of being upset by something in the documents highlights her exposure to public examination, a typical difficulty for individuals in prominent positions. The media often provides news with its own predispositions and sensationalism, which can be upsetting and frustrating to those in the public eye. Her spouse's suggestions to be "more tolerant" indicates developing a strength to such justifications, embracing an attitude of persistence and understanding instead of responding with immediate defensiveness or anger.

The imagery of a horse flicking away flies recommends an elegant and simple and easy ability to dismiss inflammations. It communicates a sense of natural ease and grace in the face of adversity. Horses, understood for their strength and calm, do not enable flies to disrupt their balance; they intuitively and calmly swish their tails to maintain comfort. Likewise, Jack Kennedy's advice appears to encourage Jackie to cultivate a psychological detachment from the irritants of public life, to not let them disturb her peace of mind.

This method promotes the concept of selective engagement and psychological self-regulation. Instead of allowing every criticism or piece of negative press to affect her, Jackie is encouraged to examine what really deserves her emotional financial investment. The metaphor, hence, is not practically tolerance however also about preserving dignity and maintaining inner harmony in the middle of mayhem.

In general, this quote embodies a philosophy of strength and composure, advocating for a state of mind that acknowledges the inevitability of external disruptions but chooses not to be defined or taken in by them. It is a tip to concentrate on what really matters, maintaining one's energy and focus for meaningful and substantial engagements.
