In his book The Dip, American author Seth Godin teaches us, from a professional perspective, how to distinguish between "The Dip" (a temporary low point) and a "Cul-de-Sac" (a dead end). He explains when to persevere and when to quit, asserting that only by learning to tell them apart can one become a competitive "winner" in the workplace.
We must understand that "The Dip" is actually a short-term setback where the situation can still be turned around. With effort and persistence, there's a chance to overcome the difficulty. Facing a "Cul-de-Sac," however, no matter how hard you dig or how much you give, it will not lead to a way out. The only solution is to step back, retrace your path, and leave.
Our lives are much the same, filled with dips and cul-de-sacs. Have you ever been bound by the traditional notion of "never giving up", or held back by pride and the unwillingness to concede defeat?
Consider a couple who have been together for years. After exhausting their novelty and patience, their daily life descends into nothing but arguments and resentment. She complains about his lack of communication and companionship; he criticizes her for lacking understanding and gentleness. They drift further apart, no longer putting each other first.
She believes their "love" will eventually resolve their conflicts and resentment. Feeling she has devoted her youth and energy to maintaining the relationship, she can't bear to walk away. So she remains trapped in limbo.
Their core conflicts – rigid communication patterns, mismatched emotional needs, and a fundamental lack of mutual understanding – cannot be resolved by a romantic dinner or an expensive gift. Accumulated resentment and disappointment have eroded any possibility of reconciliation.
Clinging to repair a relationship that is inherently broken and no longer nourishes either party is like digging day after day at the end of a cul-de-sac. No matter how hard you try to communicate (often leading to fiercer arguments), no matter how much you force yourself to understand (resulting in deeper repression), you cannot chisel through the wall as the relationship has run its course. Every attempt only depletes your remaining sense of self and deepens the pain and exhaustion for both. At this moment, true courage comes from the lucid resolve to let go.

Similarly, if you are stuck in a job that drains your passion and offers no prospects, or entangled in a toxic "friendship" that consumes your energy without nourishing you, you need a clear mind to discern whether your predicament is actually a "Cul-de-Sac" disguised as "The Dip."
For The Dip, summon your resilience and wisdom to climb out. For the Cul-de-Sac, gather your courage and clarity to turn away gracefully. Don't let the pride born of "unwillingness to lose" become the stumbling block that prevents you from walking away.
