Formally retire at least one commitment every quarter — people only add, never prune, producing portfolio dilution that compounds yearly

Why This Is a Rule

Commitments accumulate unidirectionally: you say yes to new projects, join new groups, start new habits, and add new responsibilities. Each individual addition seems manageable. But rarely do you formally end, retire, or exit commitments. The result is portfolio dilution: each year adds 5-10 commitments while removing 0-2, producing a steadily growing portfolio that dilutes attention and energy across ever-more activities. After three years, you're managing 15-30 commitments on the same 168 weekly hours, wondering why everything feels shallow.

The "at least one" minimum is a forcing function: it mandates quarterly pruning regardless of whether any specific commitment seems ready to retire. Drucker called this "planned abandonment" — the systematic practice of asking "If we weren't already doing this, would we start it now?" For most commitments more than a year old, the honest answer is "no" — but inertia, sunk cost, and social obligation keep them alive.

The distinction between retirement (formally ending, communicating exit, closing the loop) and deprioritization (moving to the bottom of the list, intending to get to it "someday") is critical. Deprioritized commitments remain in the portfolio consuming cognitive tracking overhead without receiving attention. Retired commitments are gone — the cognitive slot is freed, the social obligation is released, and the capacity is available for new commitments that match current priorities.

When This Fires

• During every quarterly review as a mandatory agenda item
• When your commitment portfolio has only grown over the past year
• When you feel overextended despite not having taken on anything obviously excessive recently
• Complements Three consecutive months on the "didn't get to" list = either restructure to create capacity or formally abandon — zombie goals drain energy (zombie goal elimination) at the quarterly strategic level and One-in-one-out for option sets — adding a new option requires removing an existing one to prevent accumulation drift (one-in-one-out) as the macro-level pruning

Common Failure Mode

"Nothing is ready to retire": every commitment seems important from the inside. The forcing function works precisely because it overrides this perception: at least one commitment must go, even if all feel important. The one that produces the least value relative to its time and energy cost is the candidate.

The Protocol

(1) During quarterly review, list all active commitments: projects, roles, memberships, regular activities, ongoing obligations. (2) For each, ask Drucker's question: "If I weren't already doing this, would I start it today knowing what I now know?" (3) Identify the commitment(s) where the answer is most clearly "no." (4) Formally retire at least one: communicate your exit to relevant parties, complete any closure tasks, and remove it from your active portfolio. (5) Note the capacity freed. This capacity is now available for new commitments aligned with current priorities (Block recovered time for priority work immediately — unallocated recovered time fills with low-value activities within weeks — block the recovered time immediately). (6) If retiring a commitment feels impossible because of obligations: this is the commitment most in need of retirement, not the one most deserving of preservation. Obligations are the mechanism through which outdated commitments survive.
