These are some of the most useful tools ever made. I've been using index cards to help think and communicate and organize and remember for decades now.
I carry 2-3 3x5 cards folded in half, in my back pocket every single day. They form a small pouch to put small paper receipts into. Jot down shopping lists, notes or reminders. Of course, there's an ever present pen for this task.
I also carry a new package of cards (or two) in my bag. Just in case some idea or conversation or thinking or project comes up wherever I happen to be.
I don't understand how anyone can live without them.
I make a habit of spreading cards out over tables and surfaces when talking through a new or poorly understood subject. It helps clarify and organize and share and talk and think more than any other tool I've ever seen.
