### Lessons from Building Hodler Inn

**1. Start with the problem, not the technology**

Railroad crews need lodging, so build for that. Blockchain is the tool, not the goal.

**2. Build for the user who doesn't care about blockchain**

If guests need to understand crypto, you've failed. Technology should be invisible.

**3. API-first always**

Every feature is an API. Others will build what you can't imagine.

**4. Iterate with real users**

Hodler Inn guests are the test lab. Real feedback beats theory.

**5. Think in decades, act in days**

Vision for 10 years out. Ship something today.
