All riches have their origin in mind. Wealth is in ideas - not money.

Collier frames wealth as a mental and creative phenomenon rather than a purely financial one. The quote argues that money is a downstream effect: durable prosperity begins with imagination, judgment, and the capacity to generate useful ideas—new products, better methods, or clearer plans. In this view, “riches” are produced by thinking that identifies opportunities and organizes effort; cash merely measures or stores the results. The emphasis also carries a self-help implication typical of early twentieth-century success literature: cultivate mindset, initiative, and inventive thinking, and material gains can follow. It’s less a denial of money’s importance than a claim about its ultimate source.
