Why slog at a job (or worst, many of them) until you are about to drop dead when, instead, you can retire in just 10 years, before you turn 40?

The story goes that one day in the winter of 1928, Joe Kennedy stopped to have his shoes shined and when the boy finished, he offered him a stock tip: “Buy Hindenburg”. Kennedy sold off his stocks right after after concluding: “You know that it is a time to sell when shoeshine boys give you stock tips. This bull market is over”. This was just before the Great Depression.
