You’ve blown it once again and you’re searching for the reason why. Why was yesterday any different than the day before? You go over the day in your mind and come up with some possibilities. One of these possibilities seems more likely than the others. So you focus your attention on it, gathering evidence for and against. What’s wrong with this approach?
First of all, how do you know that what you are focusing on is really the cause for what happened yesterday? What if you thought more like a scientist and made this possible cause into a hypothesis. In fact, it’s best if you check out some other possible causes for yesterday’s fiasco and turn them into hypotheses too. Now you can gather evidence for and against a number of hypotheses (possible causes), which makes your search for “the real cause” more inclusive.
