I think there's makings of a top-level post here, but it needs more examples from your own or others' lives. Right now it's abstract and hard to visualize; I find myself nodding my head and wanting to skip to the next paragraph. A more concrete version would make me freshly notice areas of my life in which I'm not trying things, and would make me go "hey, wait a minute, maybe I should experiment with doing particular things differently, when I go to dinner tonight with my fiance's relatives" (or whatever).

A valuable main point, though, and one that's largely been missing on LW; I hope you can turn it into something that indeed gets us to try things more.
