Unlocking the power of clear thinking: a guide to better decision-making

How often do we stop to think about how we feel?
Shane Parrish’s Clear Thinking: Turning Ordinary Moments into Extraordinary Results argues that our decisions shape our lives.

This book clarifies how we process, reflect, and act. Parrish contends that many operate on autopilot, allowing biases and emotions to dictate actions. He encourages a shift from reactive to deliberate thinking through practical mental tools that help us recognises crucial moments and make better choices.

Clear Thinking is not your typical self-help book; Parrish balances storytelling with actionable strategies, making his advice practical. One key concept is creating a “personal board of advisors,” which transformed my decision-making.

This board includes figures like Seneca for clarity and Maya Angelou for compassion. When faced with tough decisions, I consult my board, broadening my perspective.

Recognising pivotal moments 

Parrish teaches us to identify moments where clear thinking can have the greatest impact. “So much of what I thought were snap decisions,” I realised, “were moments where I could’ve paused and chosen better.”

Mastering mental models

Mental models simplify complex situations. “First Principles Thinking “encourages breaking problems into components, while “Opportunity Cost” reframes trade-offs—every yes is a no to something else.

Overcoming cognitive biases

Parrish highlights cognitive biases that cloud thinking. His strategies, like asking, “What would Epictetus say I’m overlooking?” make decisions more intentional.

Living with purpose

Clear thinking aligns decisions with values. My board reminds me to focus on what I can control and to act with empathy.

Parrish’s storytelling, using examples like the Challenger disaster, illustrates the consequences of small lapses in judgment. This book transformed my approach to challenges and priorities. Whether facing personal or professional dilemmas, Clear Thinking guides us in turning ordinary moments into extraordinary outcomes.

In today’s chaos, clarity is a superpower. With intentionality and the right tools, extraordinary results are inevitable.
