How to Decide
- List your top 5 priorities

- Visit (tourist visa) — live like local, not tourist
- Talk to expats (Reddit, InterNations, local groups)
- Test remote work if possible
- Consider 5-10 year horizon, not just now
Reality Check
Every country has trade-offs. High taxes ↔ services. Homogeneity ↔ diversity. Efficiency ↔ flexibility. Community ↔ privacy. The "best" country is where your values align with daily reality.
