WHAT IT’S REALLY ABOUT
Stop overthinking; commit to one idea and learn fast
- Searching for a “perfect idea” in the abstract is futile; real clarity comes from customer feedback and contact with reality.
- Working on multiple ideas at once produces noisy, misleading signals and prevents the depth needed to learn what actually works.
- “Going deep” means burning other options and developing near-operator-level understanding of the customer through tight loops of talking and building.
- In the AI era, stronger ideas often sit at the frontier of model capability, verticalize into outcome ownership, and aim for an ambitious end-state.
- Even if the initial idea fails, deep exploration yields unambiguous data and often reveals a better, more structural opportunity underneath.
IDEAS WORTH REMEMBERING
5 ideasYou can’t choose the right startup idea from the armchair.
The “perfect idea” only emerges after you ship, sell, and hear real customer reactions; abstract comparison of ideas usually stalls progress.
Founder-market-fit is real, but often overused as self-sabotage.
You don’t need a decade of domain experience if you’re genuinely curious and willing to go deep fast—customer conversations and hands-on work can compress learning.
Don’t hedge across multiple ideas—commit to get clean data.
Juggling ideas dilutes execution and produces ambiguous outcomes, making it easy to quit a good idea too early or persist on a bad one.
“Going deep” requires burning the other boats.
Explicitly stop the other projects, reset your narrative/brand if needed, and focus single-mindedly so your learning rate and momentum compound.
Use an operator bar: could you run the customer’s business?
Beyond interviews, you should understand daily workflows, crises, economics, and willingness-to-pay well enough to make product decisions like an insider.
WORDS WORTH SAVING
5 quotesThe problem with this approach is that it's impossible to figure out the perfect idea in the abstract. You can only figure out what you should be working on by making contact with reality and getting feedback from customers.
— Jon Xu
If you pick an idea you're curious about, go extremely deep and, most importantly, talk to customers, it's often possible to develop extraordinary knowledge in a short amount of time.
— Jon Xu
If you don't actually go deep on an idea but instead juggle it with several others, you won't get good signal about whether what you're doing actually works.
— Jon Xu
The high watermark I use to help founders answer this question is, could you actually run your customer's business?
— Jon Xu
The worst failure mode isn't being wrong. It's not making a decision, spinning your wheels, dabbling between ideas, and never going deep enough on any one of them to learn anything.
