Ask HN: What nonfiction books do you keep rereading?

Types of Books People Re‑read

  • Strong clustering around:
    • Self‑help, habits, productivity, and communication.
    • Classical and modern philosophy/psychology (especially Stoicism and existentialism).
    • Startup/business, marketing, and negotiation.
    • Technical/programming/networking references.
    • History, politics, economics, and sociology.
    • Religious and spiritual texts.
    • Biographies/memoirs and “making of” tech histories.

Why People Re‑read Nonfiction

  • To notice new details as life experience and expertise grow.
  • To recalibrate values, motivation, and “moral compass.”
  • To stay grounded or “centered” in stressful periods.
  • For concrete ROI (e.g., better salary negotiations, investing, project management).
  • As comfort reading and recurring annual rituals.

Self‑Improvement, Habits, and Productivity

  • Habit books are used as ongoing prompts; some re‑listen while commuting.
  • Implementation-intention and “tiny habits” frameworks are praised.
  • Several commenters say these systems don’t work well for them, especially with ADHD; they suspect the books miss crucial steps for neurodivergent readers and prefer ADHD‑specific advice.
  • Classic interpersonal-skills books are reread for practical guidance in everyday interactions; earlier editions are often preferred over later, expanded ones.

Philosophy, Stoicism, and Meaning

  • Stoic texts (ancient and modern interpretations) are repeatedly revisited for:
    • Coping with hardship, finitude, and uncertainty.
    • Developing equanimity, assertiveness, and resilience.
  • Some highlight existential works on absurdity and suicide as deeply clarifying yet accessible.

Business, Startups, and Negotiation

  • Startup and growth titles (on traction, lean methods, category design, “explosive growth”) are described as:
    • Ambition-raising and perspective-changing.
    • Sometimes overwhelming but educational even when not directly applicable.
  • Negotiation books are singled out for huge perceived ROI:
    • Specific tactics (precise numbers, certain phrasing) reportedly yielded large salary gains and time savings.
    • Others say they quickly forget details and must reread before important negotiations.

Technical and Professional Texts

  • Networking, systems, and programming classics are reread every few years to:
    • Re-anchor fundamentals.
    • Appreciate clear exposition and “timeless” models.
  • Some enjoy highly mathematical or theoretical works for their density and clarity.
  • Others mostly reread manuals, cookbooks, and technical references rather than general nonfiction.

History, Politics, Economics, and Society

  • Books on trade, macroeconomics, Asia’s development, and neo‑feudalism are used to understand:
    • Why manufacturing and certain policies dominate.
    • How class, power, and international imbalances play out.
  • Political histories and campaign chronicles are reread to interpret current events, with several noting eerie parallels to past crises.
  • Works on mass movements and “true believers” are revisited to understand authoritarianism and conformity.

Religion and Spirituality

  • Some treat religious texts (e.g., Bible books, Bhagavad Gita, other devotional works) as:
    • Daily or frequent guides to life and ethics.
    • Sources of cultural literacy and allusions in literature.
  • Debate appears around:
    • Whether such texts count as “nonfiction.”
    • How historically reliable certain scriptures are; one side emphasizes archaeological/ textual robustness, another points to contradictions and unfalsifiable supernatural claims.

Biographies, Memoirs, and Narrative Nonfiction

  • Tech and business biographies, “soul of a new machine”‑style histories, and musician/pilot memoirs are reread for:
    • Insight into creative and engineering culture.
    • How politics, ego, and organizational dynamics shape products.
  • Some motivational autobiographies are criticized:
    • One is seen as more self‑harm addiction than healthy discipline.
    • Another figure in a similar niche is praised as saner and more useful.

Meta‑Discussion About Recommendations

  • A few commenters object to bare title‑lists and ask others to explain why they reread a book, viewing that as the valuable part.
  • Another suggests using frequency of mentions as a rough signal of which books to investigate.
  • Some lament that many modern nonfiction books are padded; they argue much could be compressed into short essays without losing value.
