Cherish these memories. Get a hold of it and don't let go. The good and the bad. Having survived childhood, we have more than enough stories to tell. Believe it. Own it. Harvest it and share it with the world.
Generate a word list of things that pop in your head. Don't try to make sense of it now. Let your sub-conscience guide you. This list is your well of ideas waiting to be told. And told in your own way, your own voice. All you have to do is listen and write.
My word list:
The Attic The dead guy The skunk The chest The burned girl The drunk
In each of these nouns there's a discovery waiting to be found. A discover that begins with me. All I have to do is write.
How awesome is that?
