Work hard on things you think are interesting with people that you like.

There will always be lottery winners. Optimising your life around buying tickets is a pretty guaranteed way to end up unfulfilled.

sf is unique in its ability to divorce you from reality and spark delusions of what’s possible that would be insane any place else

Build it in Cursor. Vibe it in Windsurf. Spin it up on Lovable. Try Bolt. It’s just Claude Code. Use Aider. It’s a Goose app. Run it in Zed with three MCPs. Bro it’s a Glorp harness. Native to Crundle. Open Beepo. Vibe it in Jorb.

happy @ThriveCapital day to those who celebrate

[Joshua Kushner @JoshuaKushner]

Today we announce Thrive Eternal, a permanent capital holding company that will be concentrated in a small number of assets that we can own and steward over many decades.

Across Thrive Capital and Thrive Holdings, we are building and investing through a moment of exponential change; backing emerging technologies, the infrastructure that powers them, and the businesses they can transform.

Increasingly, we see a fourth category.

These are assets with qualities that cannot be replicated by technology. Iconic franchises and cultural institutions rooted in tradition, identity, and shared experience. In a world shaped by abundant intelligence where creation scales and distribution fragments, we believe they will matter even more.

Thrive Eternal is built on the belief that the most enduring of these assets share common characteristics: they benefit from long-term stewardship, they compound through cultural resonance, and they are enhanced by technology rather than displaced by it.

Our work at Thrive has always been informed and inspired by a deep appreciation for product, brand, and the ways in which consumers form lasting relationships with the things they love. We have been building towards this for a long time.

Our first partnership is expected to be with the San Francisco Giants - an institution built on more than a century of shared identity and community, and among the most iconic sports franchises in America. We have reached an agreement, subject to league approval, to acquire an ownership stake. We feel privileged by the opportunity to be long-term partners to the Giants.

I often get asked how to find the right person for a “Chief of Staff role”

The title is so vague, one basically has to create the JD first and then work backwards

[Michael J. Miraflor @michaelmiraflor]

There are people with the title Chief of Staff that are basically just calendar organizers. There are also people with the title Chief of Staff who are essentially the most qualified people to take over a business should the CEO step down. Because they know every detail. Such an unpredictable title.

@DominiqueCAPaul very exciting

[Alan Chang @alanchanguk]

This article is anti-ambition, anti-excellence, anti-merit.

Europe is falling behind, and instead of asking why we don’t produce enough generational companies, the author has decided the real threat to society is young men working too hard, competing too hard, and wanting to win.

What a joke. Nothing is easier than mocking people who are actually trying. Nothing is cheaper than dressing up resentment as moral sophistication.

The author hides behind the noble language of "inclusion" to attack the only thing that actually democratises success: an obsession with output. We are told that intense, hyper-focused teams are "monocultures" that build bad products. History disagrees. Every technological leap was forged by relentless, obsessed groups of people who sacrificed their comfort to solve hard problems. Calling that a "monoculture" is the cope of the comfortable spectator.

We are told that an intense work ethic excludes people. Is 996 for everyone? No. Does having a family change your priorities? Of course. But demanding we lower the speed limit for an entire continent just because some people prefer the slow lane is a recipe for terminal irrelevance.

The actual exclusionary culture is the one advocated by this article: a bureaucratic, HR-driven gatekeeping where you are judged on looking good rather than being good.

The people writing these pieces will never build companies that matter. They will never invent the future. They will simply stand on the sidelines, sneering at the few people still willing to do something difficult.

That is not wisdom. It is decadence.

Europe does not need less edge. It needs more. More obsession. More work ethic. More conviction. More builders who do not ask permission from people who have built absolutely nothing.
