Sam Altman on conviction, the long game, and making decisions fast

The Z Fellows Newsletter - April 20, 2026

Welcome back to the Z Fellows newsletter! Every Monday we share 3 ideas - to help you build companies, ship products, and create your life's work.

1: Sam Altman on conviction

“The most important thing is to have a clear sense of what you’re trying to do and why.”
— Sam Altman

Sam Altman has said that the single quality that separates the best founders he’s funded from everyone else is conviction. Not intelligence. Not credentials. Conviction.

Conviction means believing in your idea when the data is thin, when the VCs pass, when your co-founder wants to pivot. It means tolerating uncertainty at levels that would make most people quit.

Conviction is different from stubbornness. Stubborn founders ignore all feedback. Convicted founders absorb feedback and remain clear-eyed about where they’re going anyway.

The world runs on people who believe something before anyone else does. That’s the job.

You can’t borrow conviction. You either have it or you need to find a different problem.

2: The long game

“Be willing to look stupid in the short term.”
— Sam Altman

When Y Combinator backed Airbnb, the idea was widely mocked. “Are you really going to let strangers sleep in your house?” The early press was brutal.

The founders who build generational companies think in time horizons that most people won’t. They make decisions that look wrong today but right in five years.

Short-termism is a trap. It feels like discipline — hitting the quarterly number, managing the burn rate — but it’s actually a slow surrender of the future for the present.

Most of the decisions that will determine whether your company succeeds aren’t decisions you can make fast. They’re directions you have to commit to and hold for years.

3: Making decisions fast

“Speed is one of your biggest advantages as a startup.”
— Sam Altman

One of the most consistent traits of great founders is that they make decisions fast — and they make a lot of them. They know that in most cases, a decent decision made quickly beats a perfect decision made slowly.

Large companies move slowly because there are too many people who can say no and too few who can say yes. Startups win because they can decide and execute in the time it takes a competitor to schedule a meeting.

Bad founders mistake motion for progress. Great founders are decisive. They ship, learn, and course-correct faster than anyone else.

Speed is a compounding advantage. Every fast decision creates options. Slow decisions create debt.

Make more decisions. Make them faster. Most of them won’t matter as much as you think.
