The book in one sentence
People do not buy what you do, they buy why you do it, so start with your purpose.
About the author and the book
Simon Sinek is a British-American author and speaker. Start With Why: How Great Leaders Inspire Everyone to Take Action, published in 2009, grew from the success of his TED talk on the same topic, one of the most watched talks online. The book uses stories from business and history to illustrate its idea.
The Golden Circle
| Circle | Question | What it is |
|---|---|---|
| Why | Why do you exist? | Your purpose, cause or belief |
| How | How do you do it? | Your values and the way you work |
| What | What do you do? | Your products or services |
5 ideas worth remembering
1. The Golden Circle
Most organizations communicate from the outside in: what, then how, then why. Inspiring ones communicate from the inside out, starting with why.
2. People buy why, not what
Sinek says customers, employees and supporters connect with beliefs first. Products become proof of what you stand for.
3. Manipulation vs inspiration
Price cuts, promotions and fear can get short-term results, which he calls manipulation. Inspiration builds loyalty that lasts.
4. The Law of Diffusion of Innovation
Sinek uses this model to show that a movement grows when it wins the early adopters who share the belief, not only the broad majority.
5. Clarity, discipline and consistency
A clear why needs discipline in how you act and consistency in what you do, so that people can see and trust what you say.
