My favorite tool is asking for help. You may not think of it as a tool, but it’s something I use frequently to solve a wide range of problems, so I think it qualifies. Whether it’s saying, “I don’t know what to do next – does anyone have any ideas?” when teaching, or cold-calling people to see if they’ll host a workshop, asking for help has probably done more for me than Emacs and version control combined.
