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.This episode of The Bootstraped Founder is sponsored by Paddle.comThe blog post: https://thebootstrappedfounder.com/dont-give-up-your-assumptions/The podcast episode: https://tbf.fm/episodes/432-dont-give-up-your-assumptions Check out Podscan, the Podcast database that transcribes every podcast episode out there minutes after it gets released: https://podscan.fmSend me a voicemail on Podline: https://podline.fm/arvidYou'll find my weekly article on my blog: https://thebootstrappedfounder.comPodcast: https://thebootstrappedfounder.com/podcastNewsletter: https://thebootstrappedfounder.com/newsletterMy book Zero to Sold: https://zerotosold.com/My book The Embedded Entrepreneur: https://embeddedentrepreneur.com/My course Find Your Following: https://findyourfollowing.comHere are a few tools I use.
