How do you use Hazel?

I have always liked the idea of putting some automation in place for my files but now that I have hazel I am really struggling to find use cases that I can use to use the app.
I have looking quite a bit through the forums and none of the things really stroke me as useful for me personally. The only thing I might use this for right now is to keep files lowercased in folders I specified.
I am really curious though, what are your most ran hazel rules are and what things that you have done that really changed the way you approach using your system?
