What are some interesting things to write in your journal?

I’ve just started writing in my journal again and I’m kind of stuck with what to write. I’ve wrote about my crush, some other random stuff happening, a list of my favourite things and that’s about it. I don’t want to read it and get bored, I want to be intrigued and interested in my life. If I have a daughter in the future I plan to give it to her. What are some interesting things I can write in my journal?
