As someone with Schizoaffective Disorder Bipolar Type, if you are not diagnosed with a mood disorder, tracking "swings in you mood" when you have no clinical disorder seems like a disorder of its own.
I have had people tell me they were "manic". Then I showed them videos I took when I was manic and they see what I mean when I tell them they are not manic.
We have come to a place where we do not want even normal fluctuation in mood, and that is a illness of its own, but it is a cultural illness.
The message here was "journaling is a useful form of introspection".

Maybe for some it's a lot more extreme than for others, but even if it's not so dramatic as to be categorized as a mental illness wouldn't you want to know if, say, there were a direct correlation between whether you went for your morning run and your mood later in the day?
