“Most people think they know what they are good at. They are usually wrong. People know what they are not good at more often – and even there people are more often wrong than right. And yet, one can only perform with one’s strengths. One cannot build performance on weaknesses, let alone on something one cannot do at all.
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.”
