Excitement is produced by chemicals, "dopamine" that produces pleasure, "norepinephrine" that brings passion, "endorphins" that are responsible for pleasure and pain relief, and "endorphins" that help us overcome Difficult “Oxytocin.”

Happiness is the addition of chemicals and nerve impulses. Happiness is generally a comprehensive response of happy feelings and life satisfaction in the precuneus (University of Tokyo)

Selly Germann believes that happiness is generally realized in five forms: positive emotions, concentration, interpersonal relationships, meaning, and achievement.

Excitement: People can obtain sensory pleasure. For example, the pleasure of eating something delicious, or the pleasure of having an orgasm. This happy characteristic is: temporality and adaptability. On the one hand, sensory experiences cannot last - for example, you cannot eat a good one that always speaks eloquently; on the other hand there is - "hedonic adaptation", i.e. happiness in this area is not linearly increaseable, but It is a diminishing profit margin like an economic description: For example, if you like to eat cakes, spreading the cakes until you eat 10 pieces will bring you more pleasure than eating several pieces in a row and more than ten pieces of cake in a row. (This part is very close to the concept of excitement)

Concentration: Concentration is the proverbial "selflessness". When you do something, you have to put all your energy into it. There is only one thing on your mind, and all other thoughts and even perceived feelings are greatly diminished or even eliminated. This is a state of concentration. Psychologist Mihaly Csikszentmihalyi calls this state Flow. This is the state of mind that the average person can enjoy from a scientist's thought-provoking questions to a musician's performance of oblivion. The characteristic of this joy is: forgetting everything - hunger, fatigue, sleepiness and even time, people seem to move naturally in the river. (I don’t think this is happiness)

Relationships: Good relationships are also an integral part of happiness. Christopher Peterson, one of the founders of positive psychology, said happiness is “what’s left.” Many of the joys in life come from other people: the beauty of first love, the joy of parenting, the joy of seeing friends achieve something...and of course other things like helping others. The characteristics of this happiness are: reflection, that is, as long as you see that your behavior makes others happy, they will be happy, as if by the same reflection.

Meaning of life: People often think that "decadent", "wasting time", "boring", etc. are actually judgments of meaning. Each one has its own specific meaning in life. This is a bigger and broader problem than oneself: some may be the ultimate truth of science, others may kill each other, some may find common ground in the world, and some may be people just family and life, these are Subjective. But one thing is the same, that is, even if you have no results, behavior consistent with this meaning can bring you happiness. The characteristic of this kind of happiness is that it does not depend on the state of the individual - for example, people believe that the meaning of life is the pursuit of scientific truth. Even if his living conditions are poor in all aspects, he can do anything he wants to pursue scientific truth

Achievements: completing a thing, reaching a standard, becoming a kind of person, etc., It can also be a source of happiness for people. And focusing on different fields, the joy comes from the achievement itself: for example, some people may not like reading and do not experience the feeling of "immersion" during the reading process, but when he "processes" all the exams, the achievement of the degree certificate also It can bring him extraordinary happiness. The characteristics of this happiness are: stage and aggressiveness. One stage will pursue achievement, and after entering the next stage, it will pursue higher achievements. It is impossible to achieve a certain level of achievement to achieve the same level of achievement, nor to achieve a lower level of achievement after reaching it.

The happiness of life is compound, and the five kinds of happiness do not overlap. An ordinary person may have enjoyed more than five kinds of happiness. These five kinds of happiness together are the happiness of life.
