For the great majority of people, to know their strengths was irrelevant only a few decades ago. One was born into a job and into a line of work. The peasant’s son became a peasant. If he was not good at being a peasant, he failed. The artisan’s son was similarly going to be an artisan, and so on. But now people have choices. They therefore have to know their strengths so that they can know where they belong. There is only one way to find out: the feedback analysis. Whenever one makes a key decision, and whenever one does a key action, one writes down what one expects will happen. And 9 months, or 12 months later, one then feeds back from results to expectations. I have been doing this for some 15 – 20 years now. And every time I do it, I am surprised. And so is every one who has done this.
