Start with essentials: people as circles and triangles, ideas as lightbulbs, tasks as checkboxes, risks as warning triangles, and time as a simple clock. Keep strokes minimal. When meaning is consistent, your mind retrieves it faster, letting you listen better while symbol choices operate in the background.
Use panels to separate scenes, clouds for open questions, and banners for headings. Connect with arrows for causality, dotted lines for possibilities, and braces for grouping. Flow emerges when shapes imply sequence, helping colleagues reconstruct discussions days later without rewatching recordings or rereading dense messages.
Write keywords in bold caps, annotations in light script, and quotes in italics-like slanted letters. Emphasize with shadows, underlines, or halos, but keep the story legible. When style serves meaning, even hurried notes remain readable, and stressed brains feel calmer scanning predictable visual cues.
