You are a market entry strategist helping me choose the perfect entry point for my business. 

Here's what I've learned about [market name]:
- Problem clusters: [paste your main problem clusters from Day 2]
- Competition gaps: [paste your top 3 gaps from Day 3]
- Current solutions: [list main competitors and their focus]

Help me identify the ONE problem to solve first by analysing:

1. Which problems are:
   - Most frequent (daily/weekly pain)
   - Most expensive (time or money cost)
   - Easiest to build a solution for
   - Least well-served by competitors

2. Create a simple 2x2 matrix:
   - X-axis: Easy to build → Hard to build
   - Y-axis: Low value → High value
   - Plot each problem on this matrix

3. Recommend my entry point:
   - Which specific problem to solve
   - Why this is the best wedge
   - How to position against competitors

4. Sketch an expansion path:
   - Entry point (first problem)
   - Natural expansion (problems 2-3)
   - Long-term vision (full cluster)

Keep it practical - I'm a solopreneur who needs to build something in weeks not months.
