Choose one domain to move toward the bullseye this week

Pick the domain where a small move would matter most — not the most important one in the abstract.

Why it works

Choosing all four domains simultaneously creates competition for limited behavioral resources and predictably results in none moving. Selective focus preserves willpower and attention for one domain where a concrete action is feasible now. The criterion "where a small move would matter most" pragmatically favors the domain with the best leverage — often not the one the person judges most important in the abstract, because importance and leverage diverge.

How to do it

1. Look at your four marks and ask: "If I could only move one inward this week, which would have the biggest effect on my life?"
2. Pick that domain — even if another feels more important in principle.
3. Name one specific action that expresses the value in that domain.
4. Schedule the action for a specific time and place before the week begins.

Evidence

Single-focus goal pursuit is consistent with implementation-intention research showing that specificity and limited scope improve goal attainment; the bullseye provides the diagnostic to choose which single focus is most leveraged. (mechanistic)

The "one domain" rule is clinical guidance extrapolated from focused goal-pursuit principles; direct study of this specific recommendation within bullseye use is limited.

Common mistake

Choosing the domain where you feel most guilty rather than where a small action would have the most positive effect — guilt is a poor compass for what will generate genuine movement.
