Common Sense and Common Business Practices.Case in point.There is a theorem in Geometry: If a line intersects a circle at one point,(tangent) then a line drawn from that point to the center point of the circle will beperpendicular. (90 degrees). This makes sense. If you think about it, it makesmore sense. Common sense will say, “It seems to be impossible to be any otherway.” (Still, common sense says, “Still, it must be proved.”)One reason this must be proved is that theorems that are more complex are noteasily deduced by looking at them. Therefore, you must learn proofs.Still, common sense is a great way to avoid pitfalls. In addition, what I saidabove, contravenes what I believe. (About management, not about geometry.)I believe common sense is still the better way to go most times. However, I alsoknow that it is necessary to have some analytical support.[Remember, I make only two claims. I have an analytical mind and the ability tospeak in metaphors.]The reason why people choose common sense, however, is that people becomebogged down in analysis. This is due, in part, to a lack of common sense. Inaddition, there is an attempt to use analysis to delay implementing strategy bythose who lack sufficient analytical skills to arrive at a conclusion. Theconclusion part is what causes people to become flummoxed.Now, what gives us the courage to formulate and implement strategy?That courage is the result of experience, intelligence, education, and skill. Fromthese arise the courage necessary to form a strategy you have faith in and toexecute without the hesitation—hesitation that is rewarded with failure. Youcannot jump halfway across a stream without falling in. (And you cannot turnback in mid-air.)Another problem is the impediment of plausibility.With computers, certainly, and with calculators at the very minimum, it wouldseem unnecessary to memorise the times tables. The argument could be madethat the results of the calculator are valueless unless you know enough math torecognise the answers as the correct ones. However, that falls apart when youget into numbers larger than you might handle in the fourth grade.
