The common advice to conduct unbiased discovery interviews sounds logical but often fails. The truest way to validate an idea and understand customer needs is through the act of selling. This forces a concrete value exchange and reveals genuine demand in a way that hypothetical conversations cannot.

Standard "discovery interviews" are often a form of "playing founder." It's arrogant to believe a few 30-minute conversations can yield the deep insights needed to build a game-changing product. True understanding comes from immersing yourself in the customer's work, not just casually interviewing them.

Early-stage founders, especially those who are analytically minded, must resist the comfort of spreadsheets and data. The most crucial activity is direct engagement and selling, even if it feels uncomfortable. No amount of analysis can replace the impact of the founder personally championing the product.

Many founders perceive selling before building a product as an extreme approach. They prefer the comfort of building first, even though it wastes months on irrelevant products. This aversion stems from a fear of interrupting people without a finished product, a mindset that equates building with preparation and early selling with being premature.

Founders often create complex plans and documents to avoid the simple, hard, and uncomfortable task of selling. Just as getting stronger requires consistently lifting heavier weights, finding product-market fit requires consistently doing the core work of talking to customers and trying to sell.

Creating elaborate decks and spreadsheets provides a feeling of productivity but is often a sophisticated form of procrastination. It allows founders to delay the core, uncomfortable task of directly engaging potential customers and facing rejection, thereby making no real progress on finding product-market fit.

Forcing yourself to do uncomfortable work like cold calling is not sustainable. Founders must find an intrinsic motivation—like solving a riddle, righteous anger, or a desire to serve—that pulls them into the work, making the inherent discomfort feel irrelevant in the pursuit of a larger goal.

Founders from backgrounds like consulting or top universities often have a cognitive bias that "things will just work out." In startups, the default outcome is failure. This mindset must be replaced by recognizing that only intense, consistent execution of uncomfortable tasks can alter this trajectory.
