Think about this money choice
Imagine this situation: You invest 5000 in local currency/month at 12% annual return.
How it works
Non-linearity of compounding: at 12% return, the 30-year result is approximately 5-7× the 10-year result despite only 3× the time. This is because years 11-30 earn returns on an already-large base. The last decade of a 30-year investment typically produces more wealth than the first two decades combined.
Apply it to a real decision
Real-life money moment: You invest 5000 in local currency/month at 12% annual return. Approximately how much do you have after 30 years? The key lesson is: Future value of 5,000 in local currency/month at 12% for 30 years ≈ 17,500,000 in local currency+.
