The real return from saving small amounts when you're young isn't the modest financial gain over time; it's the formation of a crucial habit. You can't live paycheck-to-paycheck for 15 years and then suddenly decide to become a disciplined saver at age 35. The foundation must be built early.

Common wisdom to rapidly pay off a mortgage is suboptimal. Due to compounding, investing extra cash—even if the return rate merely matches your mortgage interest—will generate significantly more wealth over time. One investment compounds up while the other debt amortizes down, creating a large wealth gap.

The temptation to switch to a shiny new opportunity ignores the significant head start you've built. Even if the new venture grows faster initially, you lose years of compounded knowledge and progress, leaving you behind where you would have been by sticking with it.

While Buffett's 22% annual returns are impressive, his fortune is primarily a result of starting at age 11 and continuing into his 90s. Had he followed a typical career timeline (age 25 to 65), his net worth would be millions, not billions, demonstrating that time is the most powerful force in compounding.

Due to the long-term effects of compound interest outpacing inflation, the opportunity cost of spending money when young is massive. A single dollar saved can grow to be worth $13 in purchasing power by retirement, turning a $500 splurge into a $6,500 long-term financial decision.

The financial gain from compounding small amounts saved as a teenager is often negligible decades later. The real, invaluable return is the formation of a disciplined savings habit that provides financial security and pays dividends throughout adulthood.

The hockey-stick growth of compounding happens so rapidly that it feels unreal. Financially literate people who are mathematically independent often still seek validation because they can't psychologically accept the stunning results their own calculations show. The growth defies linear human intuition.

The most meaningful achievements (building a company, raising a family) are multi-year endeavors. In an average adult life, you only have about five or six 10-year slots for these "movements." This scarcity makes the sequencing of your life's major goals a critical strategic decision.

Buffett's legendary wealth isn't just from being a smart investor, but from being a good investor for 80 years. The vast majority (99%) of his net worth was accumulated after age 60, highlighting the insane power of long-term compounding.
