My mom got lost driving home from the grocery store last week, three miles from the house she's lived in for forty years. She still insists she's fine and gets defensive the second I bring up her memory. My siblings think I'm overreacting, but I found the stove left on twice this month. How do I get her to see what I'm seeing?

I started training twice a day, six days a week, three months ago to prep for a competition. Now I'm exhausted before I even warm up and my sleep is a mess. Is this just what hard training feels like, or have I gone too far?

I turned down a job I wanted because my dad didn't approve of it. I'm 29 and still calling him after every decision to see if it's okay. Last week I almost skipped a trip because he raised an eyebrow. When does this stop being about him and start being about me?

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.
