Parent-child structures let you zoom in and out between detail and abstraction. Every hierarchy is a compression strategy — it hides detail below and exposes summary above, letting you navigate complexity by choosing your altitude.
Choose a domain you work in daily — your job responsibilities, a project you manage, a field you study, or even the contents of your home. Write down 20-30 items that belong to this domain, each on a separate line, in whatever order they come to mind. Now organize them into a hierarchy: group.
Creating hierarchies that are too deep or too shallow. Too deep: seven levels where three would suffice, forcing people to drill through four empty intermediate layers to reach anything actionable. Too shallow: everything at two levels, with parent categories containing forty children — which is.

Any concept can contain sub-concepts and belong to a super-concept. Nesting is not a feature of special data structures -- it is a universal property of how meaning organizes itself at every scale.

Pick any concept you work with regularly -- a skill, a project, a domain of knowledge. Write it in the center of a page. Above it, write two super-concepts it belongs to (the larger wholes it is part of). Below it, write three sub-concepts it contains (the smaller parts that compose it). Then pick.
Treating nesting as a property only of 'organized' or 'technical' domains. You think 'sure, file systems are nested, but my ideas are just flat.' In practice, every time you say 'that is part of this' or 'this is a kind of that,' you are invoking nesting. The failure is not that your thinking.

Too detailed is as unhelpful as too abstract — match the level to your current need.

Pick a problem you are currently working on. Write it down at three levels of abstraction: (1) the broadest framing — what is the category of problem this belongs to? (2) your current working framing — the level where you have been spending most of your time, (3) the most granular version — what.
Getting trapped at a single level and mistaking it for the whole picture. Abstract thinkers stay zoomed out and produce strategies that ignore implementation reality. Concrete thinkers stay drilled down and produce solutions that miss systemic patterns. The skill is not choosing the right level —.

Real knowledge often has items that belong to multiple parent categories. When you force every concept into a single branch of a tree, you destroy information. Lattice structures — where a node can have multiple parents — preserve the multidimensional nature of knowledge. The tree is a special.

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.
