Avoid the "passion trap." You don't need to love your business model - you need to love the freedom it creates. Many successful entrepreneurs started with practical models that funded their dream projects later.
Instead, choose based on: - Fast Validation: Can you test it this week? - Low Risk: What happens if it fails? - Clear Demand: Do people already buy this? - Simple Start: Can you explain it in one sentence?
The best first business is rarely your dream business. It's the one that teaches you entrepreneurship with minimal risk while generating real revenue.
