The 10-10-10 rule is a simple decision-making habit. Before you commit to a choice, you ask how you will feel about it after 10 minutes, 10 months and 10 years.
The point is not to predict the future perfectly. It is to create a short pause between an emotional reaction and your action, so the choice reflects what you actually want.
What the 10-10-10 Rule Is and Why It Works
Business writer Suzy Welch made the rule famous in her book 10-10-10. One source says its author first came across the idea in the book Decisive.
The three timeframes each do a different job:
- 10 minutes captures the immediate emotional payoff or sting, such as relief, anger or embarrassment.
- 10 months shows the medium-term consequences, once the mood has passed and the results are visible.
- 10 years tests the choice against your long-term goals and values.
Most regret comes from letting the first timeframe overrule the other two. Impulsive choices feel good or safe right now, while their costs arrive later.
There is also a psychological argument. Writers such as Jeff Haden at Inc. note that the longer timeframes connect you to your future self. He cites studies linking a stronger sense of continuity between present and future self to more exercise, more saving, more ethical behavior and higher life satisfaction a decade later.
Using the Rule in Practice
The rule scales from trivial to life-changing decisions. Suggested uses range from replying to a co-worker's message to quitting a job, investing or getting married. It can also keep small choices in proportion, such as whether to eat a slice of cake or when to buy a car.
A three-step routine
One popular version of the protocol looks like this:
- Set a tripwire. Pick the emotional triggers that usually push you into hasty choices, such as anger, anxiety or fear of missing out (FOMO).
- Take a timeout. When a trigger fires, stop before acting.
- Time-travel. Ask how you will feel in 10 months and 10 years, then compare that with how you feel now.
Another framing, attributed to author Annie Duke, flips the question. Ask how you would feel today if you had made the decision 10 minutes, 10 months or 10 years ago.
Examples
- A heated email: sending a sharp reply may feel satisfying in 10 minutes, but in 10 months it may have strained a working relationship. In 10 years it is likely irrelevant, which suggests waiting or softening the tone.
- A purchase: one money-focused guide says to run the three questions before any purchase or financial commitment, and that it takes about 60 seconds.
- An invitation: a Substack post argues the rule shifts attention from fear of regret to the next concrete step, such as accepting or declining.
You can also shorten or change the timeframes for smaller decisions. Ten minutes, ten hours and ten days is one suggested variation.
Tools that include it
You do not need an app, since a notebook works. Some tools do build it in. The Decision Maker: Smart Choices app, updated in September 2026, includes a text-based 10-10-10 section alongside weighted pros and cons, a decision matrix, SWOT analysis and a decision tree. A free Notion template for the rule is also available on Gumroad.
Limits and Trade-offs
The rule is a prompt for reflection, not a calculation. It cannot tell you what to choose, and your forecasts of future feelings can be wrong.
Some other limits to keep in mind:
- It favors the long term. Sometimes the right answer is the one that matters in 10 minutes, such as rest or a moment of joy.
- It needs honesty. If you already know what you want, it is easy to answer the three questions in a way that justifies it.
- It does not replace analysis. Complex choices with several options may still need a pros-and-cons list or a matrix.
Suggested ways to judge whether it works for you include fewer impulsive choices, closer alignment with long-term goals and less regret overall. If you break the rule and regret the outcome, one source suggests a simple apology where others are affected, then moving on.
Conclusion
The 10-10-10 rule works because it is cheap: three questions, about a minute, no special tools. Its value lies in slowing you down just enough to see past the mood of the moment.
Use it on the choices that tempt you to act fast, and pair it with more detailed methods when the stakes are high.
