by Simon Sinek · 2009
The golden-circle idea: people don't buy what you do, they buy why you do it.
Worth reading? Simon Sinek's Start With Why popularised the golden circle (Why → How → What) and the Apple example is genuinely useful for branding and leadership. The science behind 'why' is thinner than he implies, but the discipline of articulating purpose is real. Skip it if you already have a crisp mission statement you live by.

Book Summary
The golden-circle idea: people don't buy what you do, they buy why you do it. It earns its place by giving you a clear lens you can apply, not just inspiration.
