My thoughts run through my fingers when I write.
I feel them take shape and become coherent, become true. Their essence is in the words, and the essence of the words is in the writings.
I only really think, really concentrate when I write. The rest of the time my thoughts are endless chains running around my head.
I once read a book about a girl who wrote. That girl wrote because only then she could think. Reading that book, I realised how true that was for me as well.
When I write, and when I talk, is when I truly think. It's easier, much easier to concentrate on something serious then. And then the thoughts run through my fingers and onto the paper, or through my tongue and onto the air. I hear them, I read them, and they're crystal clear, existing and constant.
That's why I need to write. Now I know.
