The 10-Year Legacy Test is a decision rule for selecting substantial work. First identify the problem a project solves and whether you care enough about it to remain committed when recognition and revenue arrive slowly. Then project yourself ten years forward: would you feel proud that the work consumed part of your life, and would you want it associated with your name? Reject choices driven mainly by instant gratification or likely future embarrassment. For the projects that pass, expect progress to compound through years of craft, community, proof, and adaptation rather than overnight success. The test does not predict that every long-term project will win; it ensures that the effort is anchored in a problem and contribution worthy of sustained investment.
Origin
Salau explains an Instagram post urging people to invest in legacy projects and uses Guide and long-running podcasts to show how meaningful work compounds over years.
Core principles
- 01Meaningful work takes time to mature
- 02Instant recognition is a weak selection criterion
- 03Commitment grows from caring about the problem
- 04Future pride exposes short-term compromises
How to run it
- 1
Define the contribution
Write down the real problem the project solves and who benefits if it succeeds.
Pro tip Describe the change in the beneficiary's life, not the status you hope to gain.
Watch out A project built only for recognition has a weak foundation.
- 2
Test durable commitment
Ask whether the problem matters enough for you to keep learning and adapting after the novelty fades.
Watch out Interest in an outcome is not the same as commitment to the work.
- 3
Run the ten-year view
Imagine looking back after ten years. Decide whether you would be proud of the methods, consequences, and association with your name.
Pro tip Use both pride and regret as signals.
- 4
Remove instant-gratification bias
Separate the project's durable value from early revenue, praise, or public recognition.
Pro tip Choose leading indicators that show the problem is being solved.
Watch out Slow results do not excuse ignoring evidence that the project is ineffective.
- 5
Invest for compounding
Build the craft, relationships, and assets that make the project more valuable over time.
Pro tip Review the commitment periodically while preserving the long horizon.
In the wild
Salau describes spending three years building Guide around a problem he loves. The company changed from life-skills training for high-school students to remote-team education during COVID-19, while preserving his long-term commitment to the underlying work.
→ The project adapts to a larger market without abandoning its long-term purpose.
Common mistakes
Optimizing for overnight recognition
Expecting immediate attention or revenue makes worthwhile projects appear to fail before they have time to compound.
Confusing persistence with proof
A long horizon should support adaptation around a valued problem, not blind attachment to an ineffective implementation.
Ignoring future regret
Work that pays now but produces shame later fails the legacy test even if its short-term metrics look attractive.
Is it for you?
Best for
It is best for choosing consequential companies, creative bodies of work, and career-defining commitments.
Not ideal for
It is not ideal for small reversible experiments that are intentionally designed to answer a short-term question.
