Ask HN: What HN posts inspired or changed your perspective the most?

Hi HN, I’ve been reflecting on how some ideas—sometimes from just a single post—can really change how we live, work, or think. I'm curious:

What’s one Hacker News post (or discussion) that genuinely inspired you or shifted your mindset in a meaningful way?

Whether it's a technical insight, a founder’s story, a lifestyle choice, or a random rabbit hole—I'd love to read it. Bonus if you can share how it affected you.

Thanks for sharing!
