What are good sources for "rational" (or at least not actively harmful) advice on relationships?
What sort of relationships? Business? Romantic? Domestic? Shared hobby?
The undercurrent that runs along good advice for most is "make your presence a pleasant influence in the other person's life." (This is good advice for only some business relationships.)
I was implicitly referring to romantic ones. I imagine a lot of the advice would overlap, but the quality of advice for those is particularly bad.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
