Simple questions deserve simple answers.
For that is the way life runs,
The simpleness of a subject is complemented by something much more simpler.
So why is it, 
When this question surfaces in the minds of every writer,
There is nothing simple to it.

The reason for writing is as simple as it can be.
It is like painting on a canvas board,
For every stroke of the paintbrush is a stroke of words
Painting vivid images in the minds of every boy and girl.
We as writers are giving life to the lifeless lines of paper.
For even when it's blank,
There is still an image painted through words.

The greatest invention mankind could ever think of is words.
For without them, 
Nothing could ever exist.
Without the simpleness of screaming out how blue the sky is 
Or how soft those clouds look,
Or even how beautiful a starry night sky can be,
How can we
Ever appreciate the beauty writers create on canvas boards.
For every written word on a blank sheet of paper,
Is a stroke of paint,
Creating magnificence inside a dull mind

My good sir,
When asking a writer their reason for writing should be as simple as this
But
If its too complex for your mind to comprehend,
Then, let me simplify it further.
When you ask an artist their reason for creating art,
You are merely asking their reason for existing
Asking why they are  deluding themselves on such strange fantasies
But you have yet to realize the true nature of us artists
We find many ways to escape harsh realities 
Creating picture perfect paradises
Or even amplifying how gruesome society can be. 

The reason for writing should be as simple as this.
For the simpleness of a subject should be complemented with something much more simpler.
But if it's too complex for you,
The reason why writers write is as simple as this,
Writers are artists and therefore write to create art,
Like taking a single paintbrush and painting on a canvas board
We as writers take a single pencil and write on blank sheets of paper.
