Large enough to be meaningful, small enough to be digestible - an index card is the perfect size.
The size of a:
- note
- doodle
- slide
- thought
- message
- chart
- task list
The size constraint *forces* you to be concise and clear with your writing, which forces clarity and intentionality in your thinking. This is **hugely valuable**. A good index card exemplifies the "less, but better" ethos.
Get to the point. Break it down. Say it simply. Distill and encapsulate: a winning combo.
This distillation helps you look at ideas, stories, problems, and the world in pieces. When you're overwhelmed, try pulling out some index cards.
They're cheap and small enough to be thrown away and re-done. Cards can be moved around at will. Grouped and reordered. They are dynamic. You don't have to plan in advance how they will be stored.
An index card full of content can be improved on, used anywhere, and composed together to say more.
Index cards have been used by writers, historians, sociologists, filmmakers, politicians, and students to learn, study, storyboard, write whole books, and organize their thinking.
Index cards need not be *actual* slips of paper. The index card works as a metaphor for any right-sized chunk of content:
