Pick a category you use frequently — 'productive day,' 'good meeting,' 'useful tool,' or 'interesting person.' Write down the prototype: what does the most typical example look like? Then list three items that belong to the category but feel less typical. Arrange them from most to least.
Treating the prototype as the definition. When 'productive day' prototypically means 'eight hours of deep coding,' you start classifying days with difficult conversations, strategic planning, or mentoring as 'unproductive' — even when they created more value. The prototype becomes a filter that.

Pick one category system you use regularly — your task labels, your filing structure, your mental model of your team's roles, or your definition of 'done.' Find three items that don't fit cleanly into any single category. For each, write down: (1) which categories it partially belongs to, (2) what.
Treating boundary cases as exceptions to ignore rather than evidence to examine. The instinct is to force the ambiguous item into the nearest category and move on — filing the tomato under 'vegetable' and forgetting about it. This preserves the illusion that your system is complete while.

Choose a collection of 15-20 items you currently organize in a single-dimension system — notes in folders, tasks in lists, bookmarks in categories, contacts in groups. Identify three additional dimensions along which those same items could be meaningfully classified. For each item, assign a value.
Two failure modes bracket the problem. The first is dimensional poverty: classifying items along only one dimension and treating it as sufficient. You file notes by topic and then cannot find the ones relevant to a project. You sort tasks by status and then cannot identify which ones belong to a.
