The core insight: you don't need all your money to be "safe" - only the portion you'll spend in the next few years.
Bucket 1 (Years 1–3): Cash and short-term bonds - covers 2–3 years of living expenses. Zero market risk.
Bucket 2 (Years 4–10): Intermediate bonds and dividend stocks - moderate growth with lower volatility.
Bucket 3 (Years 10+): Stocks and growth investments - maximum growth potential, decades to recover from downturns.
This structure prevents the biggest retirement risk: being forced to sell stocks during a downturn to pay bills.
