“Resilient people don’t let past investment dictate future choices. They measure value by direction, not duration.”

What would you walk away from today if you weren’t busy trying to justify the time, money, and effort you’ve already spent?

In this solo episode of Seeing Sideways, I unpack the Sunk Cost fallacy and how it quietly sabotages decisions in your work, relationships, and goals. You’ll learn practical ways to let go of draining commitments so you can choose more clearly, protect your energy, and build resilient self-leadership in a noisy world.

Key Takeaway Insights and Tools (Bullet Points with Timestamps)

[00:01:07] Decision-making in a noisy world
I introduce Part Three of Seeing Sideways, exploring how cognitive biases distort our judgment in an information-heavy, opinion-saturated world and why awareness is the first step toward clearer decisions.

[00:03:38] What the sunk cost fallacy actually is
I explain how the sunk cost fallacy keeps us clinging to plans, projects, and relationships purely because we’ve already invested time, money, or effort—even when walking away would serve us better.

[00:04:58] Everyday examples: concerts, relationships, and leadership
Through real-life illustrations—from staying at a bad concert to remaining in draining relationships or funding failing projects—I show how this bias leads us to “throw good energy after bad” instead of cutting our losses.

[00:06:02] Why the sunk cost fallacy once helped us survive
I explore the evolutionary roots of this bias: in resource-scarce environments, sticking with hard-won investments made sense, but in modern life it often deepens financial, emotional, and mental losses instead of protecting us.

[00:08:24] The real cost: stagnation and missed growth
I break down how the sunk cost fallacy creates stagnation, locking us into regret and frustration, and how it stops us from reassessing, learning, and moving toward better opportunities.

Share this episode with one person who you know is struggling to walk away from a draining project, role, or relationship—they may need to hear that letting go can be a strategic move, not a failure.
