At 40-60% delivery rates, halve commitments or double allocated time — realistic targets build self-efficacy; repeated failure erodes it

Why This Is a Rule

A consistent 40-60% delivery rate means you're planning for roughly twice what you can achieve. The instinct is to "try harder" — set the same ambitious targets and push for better execution. But Bandura's self-efficacy research shows this approach is counterproductive: each month of failing to meet targets erodes your belief that planning works, producing learned helplessness ("planning is pointless, I never hit my targets anyway"). Eventually, you stop planning altogether because the plan has become a document of predictable failure.

The counter-intuitive intervention is to lower the target until you consistently hit it. A 90% delivery rate on modest commitments produces two things that a 50% rate on ambitious commitments doesn't: (1) self-efficacy — the repeated experience of setting a target and hitting it builds confidence that your system works, making planning feel worthwhile. (2) calibration data — consistent delivery at the modest level tells you your true capacity, from which you can cautiously expand.

The "halve commitments or double time" prescription provides two levers for closing the gap: reduce scope (fewer goals) or increase resources (more time per goal). Both produce a delivery rate closer to 80-90%, which is the sustainable sweet spot where targets are challenging but achievable.

When This Fires

• When Record actual vs. planned progress as a delivery rate (%) for each goal in monthly reviews — track the ratio to calibrate future estimation's monthly delivery rate is consistently 40-60% for 2+ months
• When planning feels futile because you never complete what you plan
• When the gap between aspirational plans and actual delivery has become demoralizing
• Complements Record actual vs. planned progress as a delivery rate (%) for each goal in monthly reviews — track the ratio to calibrate future estimation (delivery rate tracking) with the intervention when the rate signals chronic overcommitment

Common Failure Mode

Aspirational escalation: "Last month I only hit 50%, so this month I'll really focus and aim for 100%." The structural causes of the 50% (too many commitments, unrealistic time estimates, insufficient slack) haven't changed. The only thing that changed is the intensity of the intention. Result: another 50% month with added guilt.

The Protocol

(1) If your average monthly delivery rate has been 40-60% for 2+ consecutive months, acknowledge: you are chronically overcommitting by roughly 2x. (2) Choose one intervention: Halve commitments (next month, commit to 2-3 outcomes instead of 5-6 — Limit monthly commitments to 3-5 specific outcomes — this forces real prioritization and prevents the effort diffusion of 10-15 simultaneous goals at the lower bound) or Double allocated time (if you estimated 10 hours per goal, budget 20). (3) Execute the reduced plan for one month. Target: 85-95% delivery rate. (4) If you hit 85%+ → your capacity is calibrated. Cautiously expand by one commitment next month. If still below 70% → reduce further. (5) Build upward from a foundation of consistent delivery rather than downward from a ceiling of aspirational failure. Hitting 3 of 3 builds more capability than hitting 3 of 6.
