In the course of a day, a Four's emotions can jump between extremes. Fours are often concerned with ideal love, longing after a kind of love that they've never experienced outside of the imagination. They also have strong ideals about themselves, which, combined with highly reactive emotions, can lead them to think terribly of themselves. This makes Fours excessively prone to envy, as they see something good in others and berate themselves for not having the same qualities. The strength of Fours is that they can see the best in others.
Fours often become artists.
