It sounds like you're focusing on a different dichotomy (positive or negative reinforcement). The two ways of thinking the article deals with are more like (for a diet goal to lose a total of 30 pounds, as an example) "I've already lost 14 pounds" or "I still have 16 pounds to lose". I think the article implies that the former is more likely to lead to congradulatory mindsets, maybe justification for slacking off, while the latter keeps focus on what you have to do to acheive your 'end game'. As far as focussing on positivity or negativity, most everyone will say think positive, because they want to be encouraging and not seem/feel mean. For yourself though, you need to discover how motivation works for you. There are definitely people who are driven by the things they hate, or at least an emphasis on what needs improvement.
