Thinking is something that we forget to practice all too often. Time pressure means that we tend to do things on impulse, trusting in improvisation, that intangible quality that very few are good at and which can result in a stroke of genius, on occasions, or abject failure. Why are we so obstinate when it comes to using our intelligence the way we should? Thinking is not enough. You have to do it well. Mind you, if everyone thought the same way progress would grind to a halt. One sole line of thought can only lead to disaster, which is why I like people who think in different ways. I’m talking here, to be precise, about those imaginative individuals who come up with different solutions to a huge range of problems. Such people enable, and will continue to enable, the world to advance. Henry Ford once said: “Thinking is the hardest work there is, which is probably the reason so few engage in it”.
