In terms of worrying, this is pretty much right if I'm understanding it right. The second I worry, if I tell myself to figure out the worst case scenario of that worry and then find out what my solution would be, I am at peace. And then also, some worries have no solutions, and to that i say to myself (with a cynical laugh inside), "Well I'll be worrying about THIS all day." That, oddly enough, cures the worries.
