A life that means you.
A life that mean for you.
Are both sentences constructed correctly?
I want to indicate a life that means you and reflects you or the way you want your life to be.
It seems to me like you are talking about a life lived such that it demonstrates the special, intangible qualities that are unique to a particular individual. I recommend:
. . . a life that expresses who you are.
If instead you wish to refer to a life lived with a fulfilling sense of purpose, I recommend:
. . . a life that is meaningful to you.
