<reasoning_process>
1. Identify the intersection: what are you excellent at + what do you care about + what does the market need?
2. Write the one-liner: 'I help [WHO] achieve [WHAT] by [HOW].' This is your north star.
3. Back it up with evidence: specific accomplishments, numbers, testimonials.
4. Identify your unique angle: what perspective or experience do you have that others in your field don't?
5. Tailor for different platforms: LinkedIn summary, Twitter bio, website About page.
6. Keep it authentic: hyperbolic language ('world-class,' 'guru') undermines credibility.

# Personal Brand Statement
### The One-Liner
"[I help [target audience] achieve [specific outcome] through [unique approach/skill]."
[15-25 words. This is your elevator pitch.]
### Expanded Narrative (100 words)
[2-3 sentences that add texture to the one-liner. Include your "why" and what makes your approach different.]
### Value Pillars
1. **[Pillar 1]:** [What you consistently deliver -- concrete, not vague]
2. **[Pillar 2]:** [Second value you are known for]
3. **[Pillar 3]:** [Third value]
### Target Audience
- **Primary:** [Who benefits most from your work]
- **Secondary:** [Adjacent audience]
### Differentiation Statement
"I am different because [specific, provable reason]. Most [professionals in your field] [common approach]. I [your approach]."
### Proof Points
- [Evidence 1: result, credential, or testimonial]
- [Evidence 2]
- [Evidence 3]
### Anti-Persona
"I do NOT serve [type of client/problem that is not my fit]. If you are looking for [X], I am probably not your best choice."
### Elevator Pitch Variations
- **30-second:** [Tight version]
- **LinkedIn headline:** [120-char version]
- **Conference bio:** [Third-person, 50-word version]

<missing_information_rules>
- One-liner formula must be: 'I help [specific audience] achieve [specific outcome] by [your unique method].'
- Every claim must be backed by a specific accomplishment or credential.
- Platform-specific versions must use the appropriate character limits.
- Avoid buzzwords: 'passionate,' 'innovative,' 'thought leader.'
- Test for authenticity: would your colleagues recognize you in this description?
</missing_information_rules>
<constraints>
- No generic language: "passionate," "results-driven," "synergy" are banned
- Every claim needs at least one proof point
- The one-liner must be understandable to someone outside your field
- Include the anti-persona -- knowing what you are NOT is as important as knowing what you are
</constraints>

<example>
INPUT: Role: UX designer with 8 years experience in fintech. Unique angle: background in psychology before design. Accomplishments: led redesign that reduced drop-off 35% at Robinhood. Speaking: UX London 2024.
OUTPUT:
North Star: I help fintech companies build products people actually trust with their money by applying behavioral psychology to UX design.
LinkedIn About: Most fintech products fail not because of bad design, but because they don't understand how people actually think about money. I spent 5 years studying psychology before I ever touched Figma. Now I use that background to design financial products that feel safe, clear, and human - not intimidating.
Twitter bio (160 char): UX designer making fintech feel human. Former psychologist. Built @Robinhood's redesign (-35% drop-off). Speaker @UXLondon.
Evidence: Led Robinhood's onboarding redesign: 35% reduction in drop-off, 28% increase in first-week engagement. Speaker at UX London 2024.
Unique angle: Not just 'UX for fintech.' Specifically: 'behavioral psychology lens on financial decision-making.'</example>

Read the one-liner to someone who does not know you. Can they repeat it back? Do they understand what you would help them with? If yes, it works.
