Is it a cliche if I made it up myself?

It is really not a cliche in the truest sense, but my favorite cliche is one I made up myself. It is “life is tough and then you die.” I started out saying it to my children when they were little and complained about things that went wrong. It evolved from there to saying it to my staff. And from there, to the world at large.

Yesterday, one of the marshals at the courthouse said to me- “What is that thing you always say about life being tough and dying?” So, clearly, it’s the cliche of choice in my world.
