Power of compounding (Compounding is the Only Math)
Time does the work nobody else will.
The power of compounding is the way growth builds on earlier growth, so that returns start to earn their own returns. In The Psychology of Money, Morgan Housel argues that this, more than brilliant stock picking, explains most large fortunes. Time is the main ingredient.
The catch is psychological. A compounding curve is almost flat for a long stretch and only bends upward late. Year to year, the gains feel small and forgettable, so people often conclude that nothing is happening and give up. Housel uses Warren Buffett as an illustration: his investing skill matters, but the long span over which he has invested matters enormously too. The boring middle years are not wasted. They are the base the later growth stands on.
The common misunderstanding is that compounding runs on autopilot. It needs continued participation. Stopping contributions, cashing out in a panic, or dipping into savings early all interrupt the process and reset much of its progress. Patience alone is not enough. Consistency is the other half.
This idea links to the next card on saving. Compounding multiplies what you put in, so the amount you set aside each month is the raw material that time works on.
Example
Two cousins start putting a small amount into an index fund each month. One stops after three years because the balance seems unimpressive and spends the money instead. The other forgets about it and keeps the automatic transfer running for decades. Their monthly amounts were identical. Their outcomes are not.

Set up or check one automatic monthly transfer into savings or investments so it keeps running without needing your attention.
