However, it's important to remember that everyone still obtains happiness from both internal and external stimuli. To quantify this happiness, consider two hills, each 100 units high. One hill represents internal happiness, while the other represents external happiness. Your total happiness is based on the sum of your position on both hills, giving a potential happiness of 200 units. Foxes are higher on the external hill, obtaining rewards such as titles, wealth, and peer approval, but they tend to be lower on the internal hill.
Hedgehogs are the opposite, climbing high up the internal hill.
And, of course, hedgehogs tend to be lower on the external hill. At this point, the problem should be obvious. Therefore, not only are you topping off on that hill, but since the slope tapers off, your energy pushes you more horizontally than vertically. Moreover, because hills are steeper at the bottom, your efforts move you more vertically than horizontally. Unfortunately, people hate the opposite hill and avoid it like the plague.
