"Building Products & The Importance of Focus: Unleashing the Power of Marginalia"

In today's fast-paced world, where new products and ideas seem to emerge every day, it can be tempting for Product Managers to chase after every shiny object that comes their way. However, in my career, I have observed that the Product Managers who truly succeed are those who stick with one idea for an unreasonable period of time. This unwavering focus is not only crucial for founders building their companies but also for VC's seeking conviction and long-term success.

To understand the power of focus, let's take a step back and explore the concept of marginalia. From ancient times, people have left their thoughts, learnings, and findings in the margins of books or documents. These marginal notes, or apostils, provide a unique insight into the minds of those who came before us. They serve as a legacy, helping us understand complex concepts and gain a deeper appreciation for the knowledge that has been distilled through the ages.

One of the most famous examples of marginalia is Fermat's claim, written around 1637, of a proof of Fermat's last theorem that was too big to fit in the margin. This mathematical note showcases the brilliance and dedication of a mind fully engrossed in a single idea. Similarly, Product Managers who immerse themselves in a single product, disregarding distractions and staying resolute in their vision, can achieve remarkable results.

In her research on the future of user interface design, Catherine C. Marshall discovered the phenomenon of user annotation of texts. She found that students in several university departments would actively seek out consistently annotated copies of textbooks at used book dealers. These students understood the value of their predecessors' marginalia, recognizing it as a distillation of knowledge that could enhance their own understanding.

The parallel between the appreciation for annotated texts and the importance of focus in building products is striking. Just as students value the insights and perspectives of those who came before them, so too should Product Managers value the power of singular focus. By honing in on one idea, product teams can delve deep into the intricacies of their product, understanding its nuances and potential in ways that a scattered approach simply cannot achieve.

Now, let's explore some actionable advice for Product Managers who want to harness the power of focus and build great products:

1. Embrace the "unreasonable" period of time: It may feel uncomfortable to stick with one idea for an extended period, especially when the pressure to innovate is high. However, it is precisely during this "unreasonable" period that breakthroughs happen. Trust in the process and give your idea the time and attention it deserves.

2. Resist the urge to be a "used car salesman": Product Managers often find themselves juggling multiple products, constantly pitching and selling. However, this scattered approach rarely leads to greatness. Instead, focus on one product at a time, becoming intimately familiar with its strengths, weaknesses, and potential. This singular focus will enable you to build a truly exceptional product.

3. Learn from the marginalia of others: Just as students seek out annotated texts to gain insights from those who came before them, Product Managers can learn from the experiences of their peers. Engage in communities, attend conferences, and read case studies to understand how others have navigated the challenges of building great products. This collective wisdom can inform your own approach and help you avoid common pitfalls.

In conclusion, the importance of focus in building great products cannot be overstated. By immersing yourself in a single idea and resisting the distractions of the ever-changing landscape, you can unleash the full potential of your product. Embrace the power of marginalia, both in the historical sense and in the context of your own journey as a Product Manager. Trust in the process, resist the urge to be a "used car salesman," and learn from the experiences of others. With these actionable advice in mind, go forth and build products that leave a lasting legacy.
