I started a thread about that article:
operate your brain
That emotions are good or bad and help you see the errors of your ways is part of the ideas in the article. But then the god or bad feelings are related to the expectations of choosen desires. So then the root starts at what do you desire? But also what to you expect? It seems to boil down to either turn your desire down or keep the desire but turn the expectation of it down. But how to turn these things down is another topic.
