If "you have to trick people into doing the right thing"; you might have to take the news with a grain of salt: other may be doing the same to you. Perhaps the doom isn't so imminent?
I weighed 300 pounds at one point, and I lived - was there any imminent need to change? I've got a buddy who's smoked since he was 14 and he's fine today - I guess all those critics who told him to quit were just shrill doomers.
Perhaps, or perhaps we don't know what the fall of civilization looks like? I remember watching a talk by Jonathan Blow where he poses that question. Did the Egyptians who built the pyramids realize when their civilization fell or did it just look like business as usual until it suddenly didn't?
