The Relationship Reinvestment Rule is Ferriss's annual allocation test for social time. Before investing in new relationships, list roughly five to ten of the most important existing ones and ask whether you spent the amount of time with each person that you wanted during the previous year. Wherever the answer is no, reinvest there first. Only the remaining capacity—the overflow—goes to new relationships. The rule favors proven trust and long history over the easy novelty of meeting more people. Ferriss pairs the review with calendar architecture: for more than twenty-five years, he says he has held an annual summer reunion near his birthday so old friends can anticipate roughly the same date. The recurring event turns relational priority into protected time rather than leaving it as an intention.
Origin
Ferriss explains the rule while answering how he would spend his final day, then describes the annual reunion he has maintained for more than twenty-five years.
Core principles
- 01Trusted relationships require deliberate time, not just good intentions.
- 02Existing deep relationships receive priority over novelty.
- 03New relationships receive only the capacity left after needed reinvestment.
- 04Recurring calendar commitments protect connection from routine busyness.
How to run it
- 1
Name the core relationships
List the five to ten people whose presence and trust matter most. Use your actual priorities rather than social prestige.
Pro tip Keep the list short enough that meaningful time allocation remains possible.
Watch out History alone does not make a relationship healthy.
- 2
Audit last year's time
For each person, compare the time you spent together with the amount you would honestly have wanted. Mark each relationship yes or no.
Pro tip Check calendars and trips rather than relying only on impressions.
Watch out Time quantity is not a complete measure of relationship quality.
- 3
Reinvest where needed
Where the answer is no, schedule the next meaningful contact or shared period before adding optional new commitments. Match the action to what that relationship needs.
Pro tip Put the next date on the calendar during the review.
Watch out Reinvestment should respect the other person's wishes and availability.
- 4
Allocate the overflow
Only after the core relationships have appropriate time should remaining social capacity go to new connections. Treat capacity as finite.
Pro tip Reserve an explicit amount of open capacity rather than assuming unlimited time.
Watch out The rule prioritizes; it does not require rejecting every valuable new relationship.
- 5
Build a recurring anchor
Create a repeatable gathering or ritual with a predictable place in the calendar. Let recurrence reduce the coordination burden.
Pro tip Use roughly the same date each year so distant friends can plan ahead.
Watch out A recurring event should serve connection rather than become another obligation nobody enjoys.
In the wild
Ferriss says that for more than twenty-five years he has organized a summer reunion around his birthday. Long-standing friends know approximately when it will happen and travel from around the country and world; he describes it as a reunion rather than a birthday celebration.
→ A recurring calendar anchor protects time with old friends from being consumed by work and new opportunities.
Common mistakes
Prioritizing novelty
Constantly adding new contacts can leave little time for the trusted relationships the person says matter most.
Keeping the priority abstract
Calling relationships important without scheduling time leaves ordinary calendar pressure in control.
Equating old with healthy
Longevity and trust can justify reinvestment, but they do not override safety or mutual willingness.
Is it for you?
Best for
People whose calendar repeatedly favors new contacts or work despite valuing a small circle of trusted friends and family.
Not ideal for
Relationships that are unsafe, coercive, or no longer healthy merely because they are old.
