 # Building
-One of the core life/work areas.
+
+The core area encompassing everything related to building and growing Refactoring as a business. This includes the newsletter, podcast, sponsorship revenue, team operations, and content strategy.
+
+## Scope
+
+Building covers the full lifecycle of running a media business as an indie founder:
+
+- **Content production** — writing weekly essays, publishing the newsletter, maintaining editorial quality
+- **Audience growth** — subscriber acquisition, retention, referral programs, SEO
+- **Revenue** — sponsorship packages, pricing strategy, sponsor relationships, renewals
+- **Podcast** — guest outreach, recording, editing, distribution, analytics
+- **Team** — managing [[person-matteo-cellini]] and [[person-paco-furiani]], weekly syncs, 1:1s
+
+## Why this area matters
+
+Refactoring is the primary vehicle for professional impact and income. Everything in this area ladders up to the long-term vision of building a sustainable, high-quality engineering media company that serves tens of thousands of senior developers and engineering leaders.
+
+## Key principles
+
+- Ship consistently — a weekly newsletter is a promise to the audience
+- Quality over quantity — one great essay beats three mediocre ones
+- Revenue follows trust — sponsorships work because the audience trusts the content
+- Build systems, not heroics — processes like [[procedure-weekly-newsletter]] and [[procedure-content-calendar-review]] keep things running even on low-energy weeks

 # Finance
-One of the core life/work areas.
+
+Personal and business finances. Covers investing, savings, tax planning, and the financial health of Refactoring as a business.
+
+## Scope
+
+- **Personal investing** — index fund portfolio, occasional individual stock research, long-term wealth building
+- **Savings** — maintaining a healthy savings rate, emergency fund, annual targets
+- **Business finances** — Refactoring revenue tracking, expense management, quarterly financial reviews
+- **Tax planning** — Italian tax obligations, VAT management, accountant coordination
+
+## Philosophy
+
+The approach to finance is intentionally simple: automate what can be automated, invest passively for the long term, and focus energy on growing business revenue rather than optimizing portfolio returns. See [[evergreen/index-funds-and-intellectual-humility]] for the underlying thinking.
+
+## Key measures
+
+- [[measure-net-worth]] — tracked quarterly
+- [[measure-savings-rate]] — target 30%+ of net income
+- [[measure-sponsorship-mrr]] — the primary revenue metric
+
+## Cadence
+
+Monthly portfolio check via [[procedure-monthly-portfolio-review]]. Quarterly deep dive via [[procedure-quarterly-financial-planning]].

 # Health
-One of the core life/work areas.
+
+Physical and mental health. Encompasses cycling training, gym work, nutrition, sleep, and recovery.
+
+## Scope
+
+- **Cycling** — the primary sport, including structured training blocks, gran fondos, and the long-term goal of riding the Stelvio
+- **Strength training** — gym sessions focused on functional strength and injury prevention
+- **Nutrition** — fueling for performance and general health, cooking as a creative outlet
+- **Sleep & recovery** — tracking resting heart rate, prioritizing sleep duration, managing training load
+- **Mental health** — recognizing burnout patterns, maintaining boundaries between work and rest
+
+## Why this area matters
+
+Health is the foundation everything else is built on. Consistent training and sleep directly correlate with better creative output, clearer thinking, and more sustainable work habits. The [[evergreen/training-load-and-knowledge-work]] connection is real and measurable.
+
+## Key measures
+
+- [[measure-resting-hr]] — proxy for overall cardiovascular fitness and recovery status
+- [[measure-cycling-km-per-month]] — volume indicator for training consistency
+
+## Cadence
+
+Weekly training reviews via [[procedure-weekly-cycling-block]]. Monthly health check via [[procedure-monthly-health-review]]. Daily gym or ride tracked as events.

 # Learning
-One of the core life/work areas.
+
+Continuous learning through reading, courses, conversations, and writing. The input side that feeds everything else.
+
+## Scope
+
+- **Reading** — books, articles, newsletters, research papers. Target of 20+ books per year
+- **Writing as learning** — [[evergreen/the-compound-effect-in-knowledge-work]] captures why writing notes and evergreen pieces accelerates understanding
+- **Conversations** — podcast guests, conference hallway chats, 1:1s with smart people
+- **Courses & talks** — occasional online courses, preparing conference talks as a forcing function
+
+## Philosophy
+
+Learning is not about consuming more — it's about extracting and connecting ideas. The [[procedure-evergreen-note-writing]] process exists to turn raw input into lasting, reusable knowledge. Every book note in [[note/]] should eventually produce at least one evergreen idea.
+
+See [[evergreen/reading-more-by-reading-better]] for the approach to reading.
+
+## Key measures
+
+- [[measure-books-per-month]] — reading volume
+- [[measure-evergreen-notes-created]] — output quality indicator
+
+## Topics of interest
+
+[[topic-ai-ml]], [[topic-saas-business]], [[topic-team-leadership]], [[topic-product-management]], [[topic-personal-finance]], [[topic-cycling-training]], [[topic-writing]]

 # Personal
-One of the core life/work areas.
+
+Personal life, family, relationships, and non-work interests. The area that keeps everything grounded.
+
+## Scope
+
+- **Family** — regular calls home, visits to [[person-nonna-lucia]], staying connected despite distance
+- **Relationships** — friendships, social dinners, maintaining a life outside of work
+- **Hobbies** — [[topic-cooking]], [[topic-music-guitar]], [[topic-travel]]
+- **Rest & downtime** — intentionally unstructured time, weekends without screens, vacation planning
+
+## Philosophy
+
+It's easy to let the Building area consume everything. This area exists as a reminder that the point of building a sustainable business is to have a good life — not the other way around. Protecting personal time is not a luxury; it's what makes the work sustainable long-term.
+
+## Notes
+
+- Dinner events with friends are tracked as recurring events — not because socializing needs to be optimized, but because it's easy to let weeks slip by without seeing people
+- Family calls are a non-negotiable weekly commitment
+- Travel planning happens quarterly, usually tied to cycling events or conferences
