Why an Investor Would Wish He Had Started Earlier
Buffett’s joke points to a feature of investing that is easy to overlook: time can matter as much as the amount invested. When an investment grows and its gains remain invested, those gains can produce returns of their own. This is compounding. The longer that process runs, the more opportunity there is for growth to build on itself.
That helps explain why an investor might look back at an early start and still wish it had come sooner. A small sum invested years earlier has more time to compound than the same sum invested later. The missed years are not just a stretch of waiting; they are years in which potential gains could also have been growing.
The Joke—and Its Limits
The humor comes from applying an adult investor’s hindsight to childhood: even a remarkably early start can seem late when measured against the decades that follow. But it is a lesson about time, not a promise that every early stock purchase will pay off. A company can falter, and investment returns are uncertain.
Buffett’s story is memorable because it makes an abstract idea concrete. Starting early creates more time for an investment to grow—and, just as importantly, more time for uncertainty to shape the result.
