Lists are useful for finding jobs, collaborators, resources, and concrete examples of progress in cause areas. You and other EA-aligned people might find it useful to have lists of, for example, innovation prizes (e.g. XPRIZE, Longitude Prize), field-specific coordination and prioritisation organizations (e.g. New Harvest, FINDdx), researchers working on biorisk, or books to read to understand key global problems.
Get into the habit of building lists of things that are relevant to your work or your thinking about EA. The lists that you keep using and adding to are probably worth sharing on the EA Forum. Check out these lists of high-potential technology organizations and effective thesis topics for inspiration. (h/t Richard Batty)
