On why we write

Why do we write?
Have you ever wondered this?
Why are we compelled to put on paper,
Our thoughts, our memories, our dreams.
 
Is it because to see them inked,
Or drawn, or digitized,
Makes our brainstorms rage,
More solid and composed,
Than mere musings in our head,
No one can see?
 
Or is it just that writing shares,
And spreads our views away,
As far as our network's networks go,
Planting a bit of us
In our collective mindframe?
 
Is that why we write?
To hold on to our thoughts enough,
For them to nurture us,
But then release them out where,
Others might inhale,
Words that where once just dust,
Formless in our brains.
