Hi David, if I've understood you correctly, I agree that a reason to return home as for other priorities that have nothing to do with impact. I personally did not return home for the extra happiness or motivation required to stay productive, but because I valued these other things intrinsically, which Julia articulates better here: https://forum.effectivealtruism.org/posts/zu28unKfTHoxRWpGn/you-have-more-than-one-goal-and-that-s-fine
I do think the messaging is a little gentler than it used to be, such as the 80k content and a few forum posts emphasising that there are a lot of reasons to make life choices besides impact, and that that is ok. This is hard in general with written content aimed at a broad audience because some people probably need to hear the message to sacrifice a little more, and some a little less.
This is a good question. I'm honestly not sure what I would have done differently overall. My guess is I would have gone back a little sooner, and invested a little more in maintaining friendships in Melbourne while away.
Thinking about this sooner also might have changed how I approached dating while in London if I would have known in advance I was always heading home.
Approx how much absorbency/room for more funding is there in each cause area? How many good additional opportunities are there over what is currently being funded? How steep are the diminishing returns for an additional $10m, $50m, $100m, $500m?
