Most people think wealth grows by adding more hustle, more assets, and more ambition. Nell Derick Debevoise Dewey, known to many as Nell 3D, built her career on the opposite bet. A subtraction mindset for building wealth is the idea behind her Substack, Subtract to Succeed, and in this conversation with Syama Bunten, she explains why the approach works.

Nell's money story began with a single childhood memory that held two worlds at once. One moment, she was having lunch at her great-grandfather's Fifth Avenue apartment. Later that same day, she was driving north to a Vermont campfire and tofu hot dogs with her mother's off-grid best friend. The split stayed with her through a decade of frontline humanitarian work in places like the West Bank, an executive MBA, and a marriage where she and her husband kept his wealth and her own distinct. The two chose access over ownership at almost every turn. She calls the trap catching so many people chrematistics, money chased for its own sake, and names the pursuit a kind of disease worth subtracting from a life.

What emerges from that critique is her own redefinition of wealth and success, where legacy is measured in intellectual and social capital rather than a number in an account. A subtraction mindset for building wealth means asking what to release before asking what to add.
