The Meaning of Meaning

What does anything mean?
What makes a thing meaningful?
Meaning is the relative importance given by a mind to an object
What can be meaningful to one can be meaningless to another
But do we really need meaning?
What are the trees meaning to do?
Does nature have a meaning or a purpose?
Why does man need a purpose?
What is the meaning of meaning anyway?
What authority will say what the meaning of meaning is?
Isn't that yet another relative construct?
Can we fathom a life that is complete at every instant and has no specific purpose at all?
