Just Keep Buying

Introduction to Consistent Investing

Nick Maggiulli shares a story about his grandfather, who spent his retirement gambling away his monthly income. Despite having a steady pension, he died with no assets to pass on to his family. If he had invested half of that money into the stock market every month, he would have died a millionaire, even during periods of poor market performance. The habit of buying assets is ultimately more powerful than trying to time the market or having perfect financial habits in other areas of life.

The central idea of building wealth is to just keep buying. This means making the continual purchase of income-producing assets a regular habit, much like paying rent or buying groceries. Income-producing assets are things like stocks, bonds, or real estate that grow in value or provide returns over time. This approach relies on dollar-cost averaging, where you buy a fixed amount of an investment on a regular schedule regardless of the current price. The most important factor is the consistency of the action rather than the specific timing of the purchase.

Technology has made it easier and cheaper than ever to invest small amounts frequently. You can now own a piece of many companies globally for a very low administrative cost. This strategy does not require predicting market shifts; instead, it relies on the long-term economic growth of the global market. Data shows that staying invested and adding money over time is a proven way to build lasting wealth. By focusing on the simple act of buying, you can reduce financial stress and let your wealth grow steadily over time.

Investing is essential today because retirement is a relatively modern invention. Before the late 1800s, people generally worked until they died, but increasing lifespans created a global need to save and invest for later years. Maggiulli identifies three primary reasons why investing is now mandatory for a stable life. The first reason is to provide for your future self when you can no longer work. Since it is hard to relate to a version of yourself decades away, research suggests that viewing aged photos of yourself can help bridge this psychological gap and encourage better saving habits.

The second reason to invest is to defend against inflation, which functions as an invisible tax on your savings. As prices for goods and services rise, the purchasing power of uninvested cash steadily declines. While cash is useful for short-term emergencies, holding too much of it over long periods ensures that your overall wealth will shrink. Investing in stocks or bonds counteracts this by growing your money faster than the rate of rising prices, preserving your ability to afford the same quality of life in the future.

The third reason is the necessary transition from human capital to financial capital. Human capital represents the value of your skills and the time you have left to work. Because your time is limited, this personal asset naturally loses value as you age and approach retirement. Investing allows you to turn your current earnings into financial assets that produce income entirely on their own. By building this pool of wealth, you ensure that once your ability or desire to work fades, your investments can take over and provide the income you need to live.
