Product management is inherently chaotic due to constant context switching, ambiguity, and difficult stakeholder conversations. Success isn't about finding a perfect process, but developing the resilience to navigate this mess and guide teams from ambiguity to clarity.

Vercel COO Jean Grosser's litmus test for a great salesperson is that engineers shouldn't be able to tell they aren't a PM for at least 10 minutes. This requires deep product knowledge, enabling sales to act as an R&D function by translating customer feedback into valuable product signals.

The core job of a Product Manager is not writing specs or talking to press; it's a leadership role. Success means getting a product to market that wins. This requires influencing engineering, marketing, and sales without any formal authority, making it the ultimate training ground for real leadership.

Ken Griffin stresses that selling is the most fundamental, yet often overlooked, entrepreneurial skill. It extends beyond customers to constantly selling your vision to candidates, vendors, and partners. He learned this from a mentor's simple plaque: "if we're all going to eat, someone has to sell."

To build trust and deliver value, product managers cannot be 'tourists' who drop in on other departments transactionally. They must become 'locals'—deeply integrated, trusted partners who are regulars in cross-functional conversations and are seen as being 'in the battle' together with sales, marketing, and other teams.

Bending Spoons' product lead argues that the ideal PM background is either entrepreneurial, which teaches focus on impactful work, or deeply analytical, which fosters an understanding of root causes. These two paths provide the core skills needed for product leadership.

A foundation in one-to-one sales reveals the human element often missing in marketing. This experience highlights the void of genuine storytelling and creativity in many marketing departments, equipping professionals to fill it with authentic, person-to-person narratives instead of just focusing on metrics.

Contrary to the popular belief that it's always detrimental, for product managers, context switching is a core strength. Fluidly moving between customer, engineering, and marketing conversations is essential for integrating diverse perspectives to bring a product to life.

Unlike corporate roles where activity can be mistaken for success, sales provides direct, visceral feedback. This "winning" mentality, born from the pain of losing a customer, keeps product leaders grounded in the ultimate goal: winning the customer, not just executing processes.
