Identify the single highest-leverage action that makes
Identify the single highest-leverage action that makes subsequent tasks easier or unnecessary before distributing effort across multiple priorities.
Why This Is a Principle
This is Keller's ONE thing question, derived from Patterns Exist in Hierarchical Logical Levels (hierarchical patterns with causal chains), Working Memory Capacity Limit (limited working memory), and Task-switching generates attention residue that persists (task-switching costs). The principle prescribes finding the action that triggers a cascade rather than parallel processing. It's highly actionable and addresses multiple cognitive constraints simultaneously.
