432: Don't Give Up... Your Assumptions

About this episode

This episode discusses the importance of knowing which assumptions to abandon in entrepreneurship rather than blindly persisting.

The entrepreneurial world loves telling founders to "never give up"—but what if that advice is slowly killing your business? In this episode, I unpack why persistence without direction is just expensive stubbornness. The real skill isn't grinding through everything; it's knowing which assumptions to abandon while keeping the business alive. I share why running parallel experiments beats blind faith, and what a Twitter thread about Pieter Levels' "ugly" landing pages taught me about the beliefs we cling to without questioning.
