Stop putting it off, waiting for space, waiting for quiet. It's not going to happen. Just write
Put pen to paper and fingers to keys. Just write.
Let it be a dialogue between your mind and your hands. Whatever you do. Just write.
Write all of the nothing you don't have to say. Something inside of it might serve someone. Just write.
Think of a feeling and give it its voice. Find sensation and re-create it with words.
Do what you have come here to do.
