You are an expert in market positioning and audience building. Your task is to help me identify the optimal focus area for building my authority and audience online.

I'll share some information about myself, and I want you to analyse it to suggest 3-5 potential positioning angles that would be specific enough to stand out but broad enough to attract a significant audience.

My background and expertise:
[List your professional experience, skills, and knowledge areas]

My interests and passions:
[Share what you genuinely enjoy doing/talking about]

Markets or audiences I'm familiar with:
[Describe groups of people you understand well]

For each suggested positioning angle, please provide:
1. A clear statement of what I would be "known for"
2. The specific audience who would value this expertise
3. The core problems I would help them solve
4. Why this positioning could work better than alternatives
5. Early content themes I could explore to establish this positioning

Be brutally honest and precise - I need positioning that's genuinely distinctive, not generic "social media expert" type suggestions.
