Every individual enjoys or experiences shifts of mood which may be subtle or dramatic (as in the case of depression, for example). Although very familiar, such shifts may be difficult to control even though engaging in particular activities may tend to induce particular moods. Individuals alternate between a relatively limited number of moods which tend to become progressively more clearly characterized.
Metaphor
