Lifestage Value Curve
Different life stages create different competitive advantages and demand different investments. The Lifestage Value Curve maps seven career-life stages from ages 10 to 80. The Golden Age (40-50) is the peak value-contribution window — not peak energy, but peak synthesis of experience, network, and judgment. Applying the wrong stage's strategy wastes each period's comparative advantage.
How it works
Output artifact: Lifestage Investment Audit + Next-Stage Unlock Plan
1. Identify current stage by age AND behavioral indicators.
· Stage · Age · Primary Demand · · ------- · ----- · ---------------- · · 蛮荒时代 Savage Age · 10-20 · Direction and first exposure · · 启蒙时代 Enlightenment Age · 20-30 · Deep skill acquisition, domain commitment · · 英雄时代 Heroic Age · 30-40 · Track record building, maximum growth investment · · 黄金时代 Golden Age · 40-50 · Synthesis, leverage, high-stakes contribution · · 白银时代 Silver Age · 50-60 · Mentoring, strategic selectivity · · 青铜时代 Bronze Age · 60-70 · Selective high-leverage contributions · · 第二蛮荒时代 Second Savage Age · 70-80 · Active choice: regeneration or stagnation ·
When to use it
- someone asks 'what should I focus on at my age,' 'I feel like I'm wasting my best years,' 'how do I plan my career long-term,' 'what does my 40s/50s demand,' or a person is clearly investing for the wrong life stage (Heroic Age execution in the Golden Age, or Silver Age coasting in the Heroic Age)
When not to use it
the problem is domain skill acquisition unrelated to life-stage strategy; chronological and developmental age diverge significantly and more context is needed first.
Worked example
Charles Darwin's Career Stages (1809-1882)
Darwin's career provides one of the most documented examples of stage-specific investment patterns producing stage-specific value.
