In my experience, various Gods choose certain types to work with. I have found that Odin, the Morrigan, Hecate, and Sekmet recruit people to Polytheism, then leave them to their own devices. Gods like the Romans ones tend go for the more experienced Polytheists.

Minerva from what I have figured out is attracted to artisans and scholars who are serious about their craft. She was one of the first Roman Gods to appear to me. Other devotees of Her are similar in outlook in their seriousness and quiet.
