The goal of early validation is not to confirm your genius, but to risk being proven wrong before committing resources. Negative feedback is a valuable outcome that prevents building the wrong product. It often reveals that the real opportunity is "a degree to the left" of the original idea.

For significant projects, ask yourself: 'Would I do this for no money or even if it meant losing money?' If the answer is yes, it's a strong signal that the intangible benefits (learning, networking, fulfillment) are massive. The best projects, like a podcast or community, often pass this test.

Before launching a major campaign, build a small, informal panel of prospects and customers you can text for quick feedback. This simple, low-cost method provides direct market validation, reduces the risk of failure, and strengthens the business case for new ideas internally.

Instead of building an MVP, pitch a one-liner about your solution to a target audience and gauge their reaction. Passionate, unsolicited stories about their pain points signal strong problem-solution fit. This method provides objective validation with minimal resources.

Never start a business without first validating demand by securing commitments from at least three initial clients. This strategy ensures immediate revenue and proves product-market fit from day one, avoiding the common trap of building a service that nobody wants to buy.

Spend significant time debating and mapping out a project's feasibility with a trusted group before starting to build. This internal stress-test is crucial for de-risking massive undertakings by ensuring there's a clear, plausible path to the end goal.

Financial metrics like '10% return on investment' fail to inspire project teams. To attract top talent and volunteers, leaders must frame projects around a compelling purpose, such as improving customer experience or sustainability. A strong purpose, not the business case, is what truly drives engagement.

Organizations suffer from an excess of priorities, a modern phenomenon since the word was originally singular. To restore focus, use the "hell yes" test: if a new initiative doesn't elicit an enthusiastic "hell yes" from stakeholders, it's not a true priority and should be dropped or postponed.

Jacobs's team uses the acronym WOTWOM—Waste Of Time, Waste Of Money—as a rapid check on new ideas. Any suggestion can be challenged with this label if it doesn't clearly contribute to organic revenue growth or margin expansion. This simple tool creates a culture focused on high-leverage activities.
