What successful people know about money: what the savings data shows, and no secret

Is there a secret that successful people know about money?

No study has found one. The source title of this page promises “insider secrets”, and books in that genre usually interview a few successful people and list what they have in common. That method cannot tell a cause from a coincidence: it never counts the people who did the same things and ended up with little. Large household surveys can, because they ask the same questions of thousands of families about their income, age, inheritances and saving.

Joseph Murphy, in 1963, offered a mental version of the secret: “Your subconscious mind is like a bank, a sort of universal financial institution.” The guide “Can your subconscious mind bring you money?” checks what his chapter promised. This page looks at the other side of the question: what the households that do build savings actually have.

Force 1: income, where the gaps are steepest

Net worth is what a family owns minus what it owes. In the Federal Reserve’s Survey of Consumer Finances (SCF), published in October 2023 with 2022 data, the median US family (the one in the middle of the ranking) had a net worth of $192,900. By income group, the medians climb steeply: $14,000 in the bottom fifth of incomes, $159,300 in the middle fifth, $747,000 for the 80th to 90th percentiles and $2,556,200 for the top tenth.

The gap is not only in what people have but in whether they can save at all. The SCF asks whether a family spent less than its income over the past year. In 2022, 82% of families in the top tenth of incomes had, against 66% in the upper-middle group and 43% in the bottom half; across all families the share was 56%. Using three US surveys, Karen Dynan, Jonathan Skinner and Stephen Zeldes found “a strong positive relationship between personal saving rates and lifetime income” (2004): households with higher lifetime incomes save a larger share of each dollar, not just more dollars. In France, Céline Antonin found the same pattern in Insee’s 2011 household budget survey: the saving rate of the best-off households rises with their permanent income (Économie et Statistique no. 513, dated 2019, published in April 2020).

Force 2: time

People save over a working life and spend in retirement, so net worth follows age. In the 2022 SCF, the median family whose head was under 35 had $39,000; families aged 65 to 74 had $409,900, the highest of any age group, about ten times more. Part of what looks like a gap between “successful” and other people is a gap between 30-year-olds and 70-year-olds.

Time also includes the years an amount stays saved. That is why the guide “How to reprogram your mind for money” starts with a standing transfer: a small amount that runs for decades beats a large one that starts late, and it needs no willpower once it is set up.

Force 3: help from family

Inheritances and large gifts flow mostly to families that already have the most. Using the SCF, Federal Reserve economists Laura Feiveson and John Sabelhaus found that the top tenth of families by net worth received 56% of intergenerational transfers, and the bottom half 8% (FEDS Notes, 2018). Inheritances of a million dollars or more were about 2% of the number of transfers but 40% of the dollars. Their conclusion: transfers play “an important role in helping to explain” how concentrated net worth is.

In France, Insee’s 2021 household assets survey (published in November 2024) found that 40% of households had already inherited at least once and 19% had received a gift (donation). Half of the households that had inherited held gross assets above €269,300, against a median of €177,200 for all households. Inheritance often arrives late: in 61% of households that had inherited, the reference person was 60 or older.

Force 4: habits and self-control, smaller than the legend

Self-control does show up in the data. In the Dunedin study, which followed 1,037 children born in New Zealand in 1972–73 to age 32, those with lower self-control in childhood had more money-management difficulties and credit problems as adults and were less likely to save, and the effect held after taking intelligence and social class into account (Moffitt and colleagues, 2011).

But the most quoted proof, the marshmallow test, is weaker than its legend. When Tyler Watts, Greg Duncan and Haonan Quan re-ran it with 918 children from a large US study (2018) and focused on the 552 whose mothers had not completed college: in that group, the link between waiting at about 4½ and school results at 15 was about half the size reported in the original studies, and it fell by two-thirds once family background, early ability and the home environment were taken into account. Waiting for the second marshmallow partly measures the home a child grows up in. Why willpower so often loses to the present, in adults too, is the subject of “Train your brain for money”.

What habits do buy is a buffer. In the Federal Reserve’s survey of household economics for 2025, 63% of US adults said they would cover an unexpected $400 expense completely with cash or its equivalent, the same as in the three previous years. A buffer is not net worth, but it is the step in this list that depends most on what you do this month.

Myth or data: a decision table

Read each row as “what is said”, then “what the surveys show”, then the part that is yours. None of this is investment advice; for a specific product, ask an independent adviser.

Derived calculation: how big are the gaps?

Our own arithmetic, from the medians published by the Federal Reserve (SCF 2022, table 2, read on 22 October 2026) and by Insee (2021 survey, read the same day). A ratio of medians compares typical families, not the same family over time.

Where the nightly ritual fits, and where it does not

The ritual cannot change your income bracket or your family’s past. It can rehearse one of the habits in the last column. We counted the four pre-written scenes of the “Money & security” area in Dream Architect on 22 October 2026: all four picture an outcome (a house by the sea, a coffee paid without checking the price, a monthly gift, a second house), and none pictures a saving step. To practise the habit instead, choose “Write my own moment” at “The moment” and write the step in the present tense, for example: “On payday I open the banking app and move a small amount before anything else.” In the full flow, “One small step” asks for a gesture of under a minute to close the evening: writing tomorrow’s transfer amount on a sticky note is enough.
