Good article on 'the power of negative thinking,' though I do think it might be more accurately entitled 'the dangers of positive thinking.' Maybe not quite the same impact . . .
Wearing rose-colored glasses, wallowing in wishful thinking, expecting to get something for nothing used to all be considered the behavior of fools -- nowadays, the positive thinking/visualization mindset pervades our culture to the point where realism is suspect and any suggestion of negative consequences is regarded as an invitation to disaster. We are exhorted to avoid any and all dire predictions lest they become self-fulfilling prophecies of doom. Time for a reality check.
