Run the two-investor comparison yourself
Use a compound interest calculator. Investor A puts in $200/month from 22 to 32, then stops forever. Investor B starts at 32 and puts in $200/month until 65. Assume the same return. Compare the balances at 65.
You’ll have:Both totals, written down.

Learn the rule of 72
Divide 72 by an annual return to get the years for money to double. At 7%, about ten years. Do it for 3%, 7% and 10% so you can feel the difference between them.
You’ll have:Doubling times at three rates.
