Index card sharing -- A good way to organize your thoughts is to write them down concisely. An index card seems like a good length for a unit of thought: longer than a quote or decontextualized summary, shorter than a story or lesson. Index cards seem a good way to transmit thoughts: it is easy to learn information presented in bite-sized chunks, each centered around some principle you can easily remember. The title of the card can act as a "slogan" for the principle.
