Organize for Discovery

S-tier programming skill: organize code and behavior such that others can discover and understand it out later without your presence/consultation.

S-tier writing skill: organize a story or idea within a story such that the reader understands or builds upon it, makes it theirs.

A-tier relationship skill: organize or set stuff down such that your partner can find it later, without needing to ask you where it is. (Riffing off Merlin Mann here, I think.)

Ergo: organizing, and empathizing, are skills worth developing.
