What is the "rule" for living things?

I think the " rule " for living things is that it have DNA and it can GROW.
If a thing can not grow by itself , I don't think the thing is living. For example : The plants are living things, and they can grow. But, look at the wooden table. It can't grow. It will look the same if you put it for 100 years. So the table is not a living thing.
Therefor, my "rule" for the living things is GROW.
