My life got worse after I found LessWrong, but I can't really attribute that to a causal relationship. I just don't belong in this world, I think.

I can imagine LW-style rationality being helpful if you're already far enough above baseline in enough areas that you would have been fairly close to winning regardless. (I am now imagining "baseline" as the surface of liquids in Sonic the Hedgehog 1-3. If I start having nightmares including the drowning music, ... I'll... ... have a more colorful way to describe despair to the internet, I guess.)
