I dunno. I've always been of the opinion that if you think positively of yourself and what you do, while taking positive action for yourself you will achieve something good for yourself.
If you sit there wallowing in self pity, your're going to drive away friends and family , interviewers will see your negative outlook and you'll continue your journey down the spiral.
The article itself reinforces that view. Those that began thinking postively AND took positive action achieved something. Those that sit there in self pity wishing something to happen are going nowhere.
