The Artist's Most Intimate

I'm starting a new series on YouTube tonight. In my new sketchbook, I have started to draw pictures with a short story, a thought or a short poem. Now I plan to film some of them. But see it yourself:

The other day I was going through all my notebooks and I was thinking about what is the most intimate thing for an artist. 
Artists process their emotions through their art. It is their outlet. The inspiration comes from experiences, pain, fear as well as joy and love. 

But the finished works of art are not the most intimate thing. They can perhaps evoke many things in the viewer and speak their very own language. But they are not the most intimate part of an artist. 
I think the most personal thing about an artist are the notebooks or sketchbooks in which all the initial ideas are captured. 
Disorganised and chaotic fragments of sentences, imprecise sketches, all mixed up.
Because it is the moment when the soul and the heart begin to speak, their pure and spontaneous language without everything having been smoothed, ordered, sorted and packaged into a finished picture, song, film or illustration.
