When I was young I thought that money was the most important thing in life; now that I am old I know that it is.
Core idea
Wilde wryly suggests that youthful idealism underestimates money, while age reveals its pervasive power over freedom, security, relationships, and practical happiness in real life.
Practical application
As an investor, respect money's real-world power early: prioritize saving, compounding, and risk management now so future freedom and security are built before life forces the lesson.
Why it matters
Wilde reveals that money, often dismissed in youth, quietly governs freedom and security, urging early financial seriousness before harsh experience proves its underestimated centrality in life.
