One of the best writers in the creative industries today, Oliver Reichenstein:
Putting Thought Into Things
"The essential tool with which to build things is your mind. Using and strengthening it hurts as much as using and strengthening other parts of your body. And as you progress, the stretching pain of improvement will stay. Listening costs nerves. Thinking is painful. Using your imagination is walking backwards into a dark and darker tunnel. The ease of following protocol comes with the disappointment of running in circles. The bittersweet pain of progress comes hand in hand with the heartache of making mistakes."
