Know Why. Know How. Then What?

“The goal is not just to sell to people who need what you have; the goal is to sell to people who believe what you believe.” — Simon Sinek

Once you know your Why and your How, the What becomes clear. Your products, services, and communications are not the reason people believe in you — they are the tangible proof of what you believe. This chapter explains how What serves as evidence of Why, and introduces the celery test as a practical filter for organizational decisions.

What as Proof of Why

Everything an organization says and does is a What. Products are Whats. Marketing campaigns are Whats. Press releases, hiring decisions, office design — all Whats. These tangible things are not the source of inspiration. They are the proof of it.

When Apple makes a computer, that computer is evidence of their belief in challenging the status quo. When Southwest Airlines offers low fares with no assigned seats, those policies are evidence of their belief in freedom and equality. The What makes the Why tangible.

The Role of What

• Products and services are proof of your Why, not the reason people are loyal
• Every What must be consistent with your Why
• When Whats are inconsistent with Why, authenticity breaks down
• People cannot see your Why directly — they can only see what you do and infer what you believe
• The clearer your Whats reflect your Why, the more trust you build

The Celery Test

The celery test is one of Sinek’s most practical tools. It is a simple filter for making decisions that are consistent with your beliefs.

“The celery test is a simple way to ensure that WHAT you do proves WHAT you believe.” — Simon Sinek

How the Celery Test Works

1. Someone recommends M&Ms for your business
2. Someone else recommends rice milk
3. Another person suggests Oreos
4. A fourth person recommends celery

Without a clear Why, you might try all four — wasting time and money on things that do not fit. But if your Why is about promoting health and well-being:

• Take: Celery and rice milk (consistent with your Why)
• Leave: M&Ms and Oreos (inconsistent with your Why, even if they might sell)

The power of the celery test is that it makes decisions easy and your beliefs visible. When you go through the checkout line with celery and rice milk, anyone can look at your cart and understand what you believe. You do not need to explain it.

Volkswagen and the Celery Test

Sinek uses Volkswagen as an example of failing the celery test. VW’s Why was rooted in being the “people’s car” — reliable, affordable, and accessible. When they introduced the Phaeton, a luxury car priced over $70,000, it failed. Not because it was a bad car, but because it was inconsistent with VW’s Why. People could not reconcile “the people’s car” with a $70,000 luxury sedan.

When Companies Fail the Celery Test

• Volkswagen’s Phaeton luxury car contradicted “the people’s car” identity
• The product may be excellent, but if it contradicts your Why, people will reject it
• Every decision — product, partnership, sponsorship — should pass the celery test
• Failing the celery test erodes trust and muddies your identity

Building Consistency

The celery test is not a one-time exercise. It is an ongoing discipline. Every decision, from major product launches to minor marketing choices, should be filtered through your Why. Over time, this consistency builds a clear, unmistakable brand identity that does not need to be explained — it is felt.

Consistency in Practice

• Hire people who pass the celery test — who believe what you believe
• Only pursue partnerships and opportunities that align with your Why
• Say no to profitable ventures that contradict your beliefs
• When you are consistent, people trust you instinctively
• Consistency compounds over time, building deeper loyalty with each decision

Key Takeaways

• Products, services, and actions (the Whats) are tangible proof of your Why
• The celery test filters decisions: only pursue what is consistent with your beliefs
• Consistency between Why and What builds trust and makes your beliefs visible
• Volkswagen’s Phaeton failed because it contradicted their identity as “the people’s car”
• Every organizational decision should pass the celery test
• When your Whats consistently reflect your Why, people trust you without needing an explanation
