For founders who’ve thought, built, executed, and have users - what’s your mindset advice?

Coming up with Ideas is hard. Execution is harder. Getting users is harder still.

If you’ve been through the full cycle - from idea to product in people’s hands - you know it’s not just tactics that matter. The mindset you carry shapes every decision, pivot, and late-night problem you face.

So I’m curious:

If you’ve built, shipped, and grown something, what’s the one mindset shift that made the biggest difference for you?
