Over the past year I worked closely with 10 founders. The 3 who moved fastest had one thing in common: when data contradicted their decision they changed course the next day. No ego no "I already committed to this." The 7 who struggled were often smarter better at arguing their original position more attached to the first plan.

This isn't a scientific study it's 10 people but the pattern was hard to ignore. The ability to change your mind quickly seems to matter more than the ability to defend your first idea.

So for those who've worked with or observed founders: have you seen this too or is consistency more important than speed of changing your mind? And the harder follow up: when was the last time you changed your mind within 24 hours of seeing data, and what did it cost you to do it?

I spent a full week forcing myself to use just one plain app for all my daily notes tasks and bookmarks instead of jumping between three specialized tools.

I was shocked by how much of my old "work" was actually just manually syncing data between apps and tweaking productivity layouts.

I keep rewriting the same awkward email friendly at first, firmer two weeks later and I hate every minute of it.

The tools I've looked at want me to move my books into Xero or QuickBooks first, which is a much bigger change than I'm willing to make for this.

Curious how others handle it: do you chase manually, use a tool, or just let smaller invoices slide? And does what you do actually work?

Google Research released Harness2, and I think it reiterates an important direction for AI-native applications.

The idea is that the model isn't necessarily what needs to improve. It's the harness around it: prompts, tools, memory, skills, and orchestration.

Harness experiments with automatically improving that harness based on how agents perform on tasks, without retraining the underlying model.

I've started asking one thing before I give anyone advice about their product. Do you want me to help you think, or do you want me to tell you what I would do?

They are completely different conversations and most of the time people want one and receive the other.

Someone bought my product a year and a half ago. Paid once. Never upgraded. Never asked for anything.

Then they emailed me out of nowhere with a detailed explanation of a problem they'd solved with it. Something I'd never thought it could do. They'd built a whole process around it and wanted to tell me.

We had a whale client who paid us more than anyone else but they sucked up almost all of our support bandwidth with constant custom demands and emergency calls.

Dropping them felt terrifying because of the revenue hit but it instantly freed up the team to actually fix our core product bugs. Three months later our churn dropped because the rest of the users finally got a stable app.

I used to respond to every Slack tap or shoulder tap instantly thinking it was just part of being responsive.

After tracking it for a week I realized every "two-minute question" actually cost me 15 minutes of context switching and broken focus.

Moving to dedicated check-in windows twice a day completely saved my deep work time, and surprisingly nobody complained about the slight delay. How do you protect your focus hours from endless ad-hoc interruptions?

I used to answer every message within an hour. Email, support, DMs, comments. I wore it like a badge.

Then I let some things sit. Not everything. Just the ones that weren't urgent, weren't from customers, weren't actually about the work.
