You might be able to figure out everything you need about moods and emotions by observing yourself and others.
If you want to understand them better, you can think about them in a larger context, possibly including an evolutionary context (asking about what purpose the emotion or mood might have served) or more. The amount of context you need depends on how well you want to understand them. Knowing about neurotransmitters and hormones isnât necessary for a good understanding.
Neurotransmitters and hormones can add to understanding, but they arenât necessary. Itâs better to start from experience and from a bigger picture, and then the smaller details can be added in if wanted or needed for a specific purpose. The details might then also refine the bigger picture.
Just focusing on the small details too much and too soon is likely to mislead.
