How to not find product market fit :D

The point of MVPs is to trade polish for faster iteration times through faster feedback.

The problem: You share something that you know is subpar and that creates anxiety.

I reframe it as validation: Somebody wants this to work. And then transform the anxiety to a drive.

Not to brag but... I had a 100/100 sleep score the other day 🙃

My resolution for 2026: Research one area of life every week and distill the 80/20 actionable ideas.

First post is sleep and the techniques for the 100/100, but we'll be pretty holistic.

Conference hack: Wear earplugs. Was listening and talking this weekend nonstop and didn't feel exhausted in the evenings.

[Christoph Hartmann @heychristoph]

When you #hustle so much you get "best networker" status at a conference hahaha

@artman I have this paranoia that I have a catch-22 in there somewhere where I use Google for 1Password and 1Password for Google and it's over

[Christoph Hartmann @heychristoph]
