Life Progress & the Value of Time
How are life stages divided?
Modern psychology and sociology divide life into these stages (by age):
- Ages 0-6 (childhood): growth and foundational learning
- Ages 7-17 (adolescence): education and worldview formation
- Ages 18-35 (young adulthood): career start and family building
- Ages 36-50 (midlife): career peak and heaviest family duties
- Ages 51-65 (pre-retirement): career transition and retirement prep
- Age 66+ (retirement): enjoying life
China's average life expectancy is about 78 years — see how much of yours you've traveled.
The irreversibility of time
Unlike money, time has three irreversible traits:
- It can't be stored: time unused today is simply gone
- It can't be substituted: no one can live your 24 hours for you
- It can't be increased: lifespan is capped, and each day's 24 hours are a fixed quota
Grasping "time as an asset" makes every present choice weightier.
The Time-Management Matrix
Sort daily tasks into four quadrants by importance and urgency:
- Important & urgent: handle now (crises, deadlines)
- Important, not urgent: planning (learning, health, relationships)
- Urgent, not important: delegate (most daily interruptions)
- Neither urgent nor important: cut the time (doomscrolling, idle chatter)
The expert's secret: invest more in quadrant two so quadrant-one fires shrink.
Practical tips for better days
A few simple, effective methods:
- Track your time: log a week with an app to find your "time black holes"
- Set small goals: 1–2 concrete goals a month (learn a skill, read two books)
- Deep work: 1–2 hours of uninterrupted focus each day
- Review regularly: check goal progress weekly or monthly and adjust
- Invest in relationships: time with family and friends — life's most important "asset"
