I missed the game-winning free throw in the district final last week. My teammates said it's fine but I can still hear the crowd groan. I have a bigger game in ten days and I can't shake the feeling that I'll choke again

We have 8 months of runway left and I'm about to start raising our seed round with zero investor relationships built up. Everyone tells me to start pitching six months before I need the money, but I'm already behind that. I don't know if I should raise now while we're weak or wait until we have better numbers

Three people told me before 9 a.m. that their request can't wait. I have time for one. How do I choose who gets it without looking like I dropped the others?

My college roommate and I used to talk every day. Now it's been four months since she answered a text. I keep replaying our last conversation looking for what I said wrong

The honest answer: if you're not sure, you probably don't have it yet. When you truly have product-market fit, people are fighting to get in. You're not questioning it.

The clearest signal is retention: are the people who try your product coming back without you having to push them? If they are, you likely have product-market fit for a segment. If they aren't, the rest is noise.

Make it a conversation

You can ask
“What about me?”

Go beyond reading or watching. Ask their Delphi a question, bring your own context, and follow the ideas that matter to you.

Explore a different angle, ask why, or dig into how something applies to your situation.

If you're not sure, you probably don't have it yet. When you do, people are fighting to get in. Start with the Sean Ellis “very disappointed” survey and look hard at retention. Those two give you the clearest read.
