We Think Ourselves In To Being

"Human beings, by changing the inner attitudes of their minds, can change the outer aspects of their lives."
-- William James (1842-1910), American psychologist and philosopher trained as a medical doctor

I've always believed that so a man thinketh so is he (Proverbs 23:7). Unless you are mentally disturbed, all thoughts, whether it be good or bad, originate with a thought and manifests itself in the things we do. Also, when people are judgemental or accusatory of others' actions I think they come to that conclusion because somehow they have identified with something that person has done and automatically become suspicious of their intention because they can relate.

Is this far of a stretch? If you think good you expect good. If you think bad you expect bad. Fair enough?
