I am trying to journal daily in the morning or in the evening. But this is a new and wierd concept to me. Do I write what I plan to do that day? My frustrations? My goals?

If one could write a prompt for your daily journal what would it look like?

Is the journal supposed to be a safe space where I just throw all my emotions so that I can handle them better during the waking hours? Like a male diary?

EDIT: I looked at the comments and I guess I am overthinking it. The point of a journal is to make it whatever the fuck you want it to be. I guess the answer then is to flow and write whatever I want. Any other responses are welcome
