Extroverts are like surface runoff. Introverts are like rivers fed by groundwater.

Extroverts instantly pour out their inner self in one go: like streams of rainwater after rain. Introverts communicate slowly and intently: like spring water welling up from deep underground.

Two key categories in personality tests are “introvert” and “extrovert”. Although it is true that we tend toward a certain pattern of behaviour which can be labelled as “introverted” or “extroverted”, no person is completely one or the other - it is a spectrum. Swiss psychoanalyst Carl Jung gave the following definition: “Each person seems to be energised more by either the external world (extraversion) or the internal world (introversion).” 

1. Extroverts are like surface runoff after heavy rainfall.

When there is an excess of stormwater or meltwater (external influence), it forms a stream. This flow is strong at first but quickly dries up after the external influence is no longer present. In the same way, extroverts get energised by social interaction but are prone to mood dips during periods of “drought” in their social life. Famously, when asked a question extroverts first speak and then think: everything comes out at once, just like surface runoff.

2. Introverts are like rivers fed by groundwater.

A river valley rich in groundwater provides a steady inflow to the river over extended periods of time. While the river is still affected by external factors (water levels rise and drop seasonally), the regular groundwater flow ensures that the river will not dry up. Similarly, introverts source their energy from their internal world. While introverts may occasionally get overwhelmed by prolonged social interactions, all the tools they need to recharge are within themselves. And when asked a question, introverts first think and only then speak, like the slow discharge of groundwater into a river system.

The Sun and professors send out energy into the universe

By George ILIEV
CorporateNature Metaphor Series, No 92

The Sun loses 135 trillion tonnes of mass every year as it is converted into energy and radiated out into the universe. This is the product of the nuclear fusion equation: four hydrogen atoms are fused together into a helium atom and energy is released in the process.

In a similar way, professors or teachers send their energy into space when lecturing. At the basic physics level, this happens by generating sound waves with their voice. At the metaphorical level, this happens by making light bulbs go on inside student heads.

The Sun doesn't only lose energy and mass: large amounts of dust, comets and asteroids fall on it every year. Similarly, professors also benefit from student feedback during discussions and may get the occasional light bulb go on in their own head.

Entrepreneurs approach opportunities in two ways: like monkeys or like chimps

By George ILIEV
CorporateNature Metaphor Series, No 73.

Capuchin monkeys and chimpanzees both enjoy eating nuts (see documentary video below). Cracking a nut open is no rocket science but for a monkey (or even a human toddler) it can be quite a challenge.

Monkeys waste a lot of energy bashing rocks against the nut without seemingly learning much from each attempt. Chimps and other great apes, on the other hand, plan and execute the blow to the nut shell with precision learned from watching others in the family. Thus, chimps often manage to crack the nut with a single strike.

Some entrepreneurs adopt the monkey approach to tackling problems and opportunities. Others take after the chimps. Younger entrepreneurs are generally more likely to follow the "monkey way" of cracking nuts: multiple trials, multiple errors, slowly learning from their own mistakes and expending a lot of energy in the process. Mature entrepreneurs are more likely to resemble chimps: having observed others for a long time, they have learned from these observations which nuts to tackle and which to leave aside, and how best to crack the nut with the least amount of energy.

Yet, whether you are a monkey or a chimp, when you reach a nut (an opportunity), you'd better start cracking it as best as you can. Or else another species will eat it.
