Engineering first principles involve breaking down complex problems into their most fundamental parts and methodically solving each component. This approach, pioneered by innovators like Elon Musk and used extensively in scientific and engineering disciplines, can transform how we tackle challenges in our daily lives.
First principles thinking starts with identifying the fundamental truths of a situation and building solutions from the ground up. Instead of relying on existing assumptions, analogies, or "the way things have always been done," this method requires examining the bare facts to develop innovative solutions grounded in reality.
Consider how SpaceX revolutionized space travel by questioning the assumption that rockets must be expensive. By breaking down rocket costs to raw materials and manufacturing processes, they identified that rockets should cost a fraction of traditional prices—leading to reusable rocket technology.
Recognize what you're taking for granted. Ask yourself: "What beliefs am I accepting without question?" Often, our biggest limitations come from unexamined assumptions rather than actual constraints.
Test their validity through research, experimentation, or seeking alternative perspectives. Just because something has always been done a certain way doesn't mean it's the best or only way.
Strip the problem down to indisputable facts and basic components. Focus only on what is absolutely true and necessary, removing layers of convention and complexity.
Use these foundational truths to construct new solutions that address root causes rather than symptoms. This often leads to breakthrough innovations rather than incremental improvements.
Traditional financial advice often relies on general rules of thumb. First principles thinking reveals more effective approaches:
Break Down True Costs: Instead of accepting broad expense categories, examine each component:
Housing: Separate mortgage/rent, utilities, maintenance, insurance, and taxes to identify specific optimization opportunities
Transportation: Compare actual costs of car ownership (depreciation, insurance, maintenance, fuel) versus alternatives like ride-sharing or public transit
Subscriptions: Evaluate each service based on actual usage and value delivered, not perceived convenience
Evaluate Investment Fundamentals: Rather than following popular investment trends, understand:
What drives long-term value creation in companies
Your actual risk tolerance based on financial goals and timeline
The true cost of fees and taxes on different investment vehicles
First principles thinking becomes increasingly powerful as you develop the skill. Each problem you solve this way builds your ability to see through complexity and convention to identify what really matters. Over time, this approach leads to more innovative solutions, better decision-making, and often significant competitive advantages in both personal and professional contexts.
By consistently applying engineering first principles to everyday challenges, you'll find yourself making more informed decisions, solving problems more effectively, and often discovering opportunities others miss entirely.
