Healthy emotions are appropriate to experience it is also critical to enable us to form accurate perceptions. The philosopher crisippus used an analogy to illustrate the difference between healthy emotions and unhealthy emotions. Let's say a person chooses to run down a hill. If they're not able to stop or change direction while running down the hill then they're running too fast. This is similar to unhealthy emotions. Whereas healthy emotions allows you to run down the hill at a speed that enables you to stop and make turns without losing where you're at or where you're going.

In the book

The Stoic Chrysippus pictured a man running down a hill: if he is moving at a speed where he can still stop and turn, his emotion is healthy; if he is going so fast he can no longer stop or change direction, the emotion has become unhealthy and has stopped his reason. Healthy feeling lets you keep your footing while you run; unhealthy feeling sweeps your legs out from under you. The core emotions themselves — anger, sadness, fear, disgust, joy, excitement — are neither good nor bad; each is simply a program with an impulse attached, and each is felt first in the body, not the head: the clenched stomach, the hot face, the tight chest. — The Heart in the Cockpit (Emotion/Awe/Anxiety/Regret/Empathy)
