My 25-year engineering career retrospective

Note-taking and tools

• Several commenters relate to frequently switching note apps; some default back to simple options (e.g., built-in system notes).
• Others highlight specific apps that “hit the sweet spot” for them: cross-device access, Markdown, calendar integration, links, and especially raw speed are praised.
• No consensus “best” tool emerges; preferences are highly individual.

Sleep, health, and productivity

• Strong disagreement over the claim that sleeping 4–6 hours regularly can cut life expectancy by “30–40 years.”
  • One side calls this alarmist and cites meta-analyses showing modestly increased mortality with short sleep.
  • The other side stresses population-level risk: even a small average reduction implies some individuals dying much earlier; analogies are made to not wearing seatbelts.
• Multiple commenters report real harms from chronic sleep loss (heart attack, stress, reduced cognition, bad mood).
• Several emphasize that 7–9 hours of sleep correlates with their best work; some function well with late schedules as long as total sleep is adequate.
• A few mention popular sleep books and critiques; some say they overstate risks, others say they’re persuasive.

Career strategy, passion, and money

• Some with ~20–25 years’ experience say: follow interests, sleep more, value relationships, and avoid obsessing over “hyper-productivity.”
• Others argue “follow your passion” is incomplete:
  • Many people lack a single clear passion.
  • Some passions (e.g., certain arts) have poor job markets.
  • Practical framing: choose among your multiple interests the ones that are economically viable, and make sure you can at least “pay the bills.”
• Several stress that money enables life choices (family, travel, hobbies), even if it’s not the main source of meaning.

Work–life balance and health

• Frequent themes: prioritize mental and physical health; go outside daily; maintain posture; avoid sitting too much; sleep well.
• Back care and strength training (or bodyweight, walking, running, yoga) are emphasized, especially for sedentary developers.
• Many refuse on-call work without significant compensation; some simply say “no” and report this as sustainable in typical business software roles.
• Multiple commenters advocate reduced hours (not really working 8h/day, four-day weeks) and say output did not suffer.

Views on the article and “career advice” genre

• Some find the retrospective useful for younger engineers; others find it sad, overly grind-focused, or sleep-depriving.
• There is skepticism about “thought leader”–style writing and perceived self-promotion, especially when the concrete details of the author’s actual engineering work are unclear.
• A few meta-comments note that most advice is autobiographical: people tend to recommend others become more like themselves, which may or may not fit different personalities and circumstances.

Soft skills, advancement, and regret

• One thread argues that technical focus alone can stall careers; people who invested in charisma, self-promotion, and “telling the right story” often reached director/VP roles.
• Recommended skills: dressing well, small talk, understanding what stakeholders want to hear, and framing contributions to appear larger (within plausibility).
• Others push back, saying they’re happier as senior individual contributors without managerial responsibilities, even if it means less status.
• Several long-timers say their main late-night regrets are more about personal life than missed career moves; others say they don’t dwell on career regrets at all.
• Overall, many stress: work is not everything; tilt the scale toward life, family, hobbies, and long-term health.
