I is for IMAGINATION...
I've written from A-G on what every good writer needs, but without imagination you are a voided soul.
Imagination is more important than knowledge.
Albert Einstein had it correct. Imagination is more important than knowledge.
Now, granted it does take some knowledge to write, but where would that knowledge be without imagination.
You have to have imagination to create characters, dialogue, scenes and endings.
Imagination carries you through your writing.
It is what makes you a great writer.
Let your imagination run wild, run amuck, run free....
