In the same way that we can become connoisseurs of fragrance, wine, food, and cars, we can become connoisseurs of emotion. Connoisseur: 'an expert judge in matters of taste'. To non-connoisseurs of fragrance, wine, food, and cars, there appears to be under 100 different kinds of them. But to the connoisseurs, there appears to be endless kinds. You'll discover that it's with emotion.
In the same way that detail is found upon closer inspection, the nuances of emotion are discovered during time spent observing emotion in real-time.
Under close inspection, emotion appears less like a spot painting, and more like a dot painting.
All the time, emotions are on. See if you can stop feeling any kind of emotion.
Remember that it is often a great benefit to us that we avoid doing things because we get a bad feeling from it- like rejecting a guy who seems needy and desperate.
