Going deep in one branch versus wide across many branches are different strategies with different costs — and the right choice depends on whether you need resolution or coverage.

Pick one project or goal you are currently working on. Write it at the top of a page. Decompose it into 2-3 sub-components. Then decompose each sub-component until you reach items that are concrete enough to do in a single sitting without further clarification. Circle those leaf nodes. Count how.
Confusing intermediate categories with actionable work. You reorganize your project plan, refine your goal categories, and relabel your folder structure — all of which feels productive but produces no leaf-level output. The hierarchy gets more elegant. Nothing ships. The symptom is a system that.

Pick one domain of your life — career, health, a side project, a relationship. Write down the single deepest assumption that everything else rests on. Not a tactic or a preference — the foundational belief. Now ask: if this root concept were wrong, what would collapse? What would suddenly make.
Treating a root concept as self-evident because everything you've built on top of it seems to work. The very success of the downstream structure makes the root feel more true than it is. You stop questioning it precisely because so much depends on it — and that dependency is exactly why.

Take a hierarchy you use daily — your file system, your task manager, your note-taking structure, your email folders, your team org chart. Count the maximum depth: how many levels exist between the root and the deepest leaf? Now ask two questions for each intermediate level: (1) Does this level.
