At the start of my vacation I closed my laptop and went back to pen and paper. To get at the heart of things, nothing beats an empty sheet of paper and a clear schedule. I spent many weeks drawing objects and scenes, and deriving geometrical formulas with pen and paper. Don’t get me wrong, I am devoted to my computer and the internet. I would be totally lost without them. But each and every day, I spend my energetic and creative hours sketching and scribbling on paper.
