'Ground-breaking' means that something is radically new and innovative. 'Ground zero' refers to the site of an explosion or some other disaster.
'Ground-breaking' is an adjective, but the words can also be separated and used as a noun and a verb. I would suggest what you want to say is:
'You are breaking new ground these days.' This means that the person you are addressing has discovered an innovative way of handling a situation.
