Sethi presents a target-date fund as a simple example for beginners who do not want to select and rebalance many investments. The investor estimates a retirement year, researches a low-cost fund carrying that date, checks that it is suitable, and automatically contributes every month. The fund holds a diversified portfolio and adjusts toward a more conservative allocation as the target year approaches. The mechanism removes repeated selection and timing decisions while preserving the benefits Sethi emphasises: consistency, time, diversification, and low fees. It is not a promise of gains or a universal product recommendation. The investor still needs to check the fund, account, costs, tax treatment, and personal risk needs, then continue contributions through ordinary market noise.

How to run it
- 1
Define the time horizon
Confirm that the money can remain invested for the long term and estimate the year retirement withdrawals may begin. Keep nearer-term needs in an appropriate savings vehicle.
Watch out Investments can fall and should not replace accessible emergency money.
- 2
Research the dated fund
Look for a target-date fund near the retirement year from a reputable provider available in your jurisdiction. Review its asset mix and glide path.
Pro tip Compare the actual fund rather than choosing from the date in its name alone.
Watch out Products and tax treatment differ by country and account type.
- 3
Check the costs
Inspect the expense ratio and any account, advice, or transaction fees. Prefer a low-cost route when the funds otherwise fit the objective.
Watch out Small percentage fees can have large cumulative effects.
- 4
Automate the contribution
Choose an affordable monthly amount and schedule it to invest automatically. Verify the first contribution actually purchased the fund.
Pro tip Begin with an amount you can sustain and raise it later.
- 5
Stay consistent
Continue through routine market fluctuations and review the setup periodically rather than reacting to every headline. Update the plan when the life goal changes, not because the news is noisy.
Watch out Consistency does not eliminate investment risk.
In the wild
Sethi uses the example of choosing a Vanguard, Fidelity, or Schwab 2050 target-date fund for someone expecting to retire around 2050. The person then sends money automatically each month while the fund diversifies and gradually adjusts its allocation.
→ The investor gets a repeatable long-term process without manually selecting and rebalancing multiple holdings.
Common mistakes
Treating simple as risk-free
A one-fund process can still lose value and must be assessed for suitability, costs, and time horizon.
Chasing constant commentary
Sethi argues that consistent contributions, time, and low fees matter more than repeatedly reacting to financial media noise.
Is it for you?

It is best for long-term investors with access to an appropriate low-cost target-date fund and a suitable investment account.
