Use the minimum information principle to keep each card focused. Make questions specific, answerable, and falsifiable. Prefer why and how over what when nuance matters. Add hints only when necessary, and avoid trivia that never connects to action. Reference a canonical note so confusion immediately leads to clarity, reinforcing a dependable loop between retrieval, explanation, and deliberate practice.
Include contrasting cases, visual anchors, and real constraints to nudge the brain toward flexible understanding. A pharmacology prompt might pair mechanisms with side effects; a coding prompt might require tracing state through a function. Rotate contexts, interleave related domains, and occasionally reverse direction by asking for causes from effects. This prevents brittle recall and strengthens pattern recognition across messy realities.
Bloated wording, duplicated content, and vague answers quietly erode motivation. When a prompt frustrates you twice, refactor it. Split compound ideas, tighten verbs, provide an exemplar answer, or replace the card with a better representation like a diagram or checklists. Keep a small backlog of repairs, and celebrate each cleanup as future you earning interest on present effort.
