This is a call to the perfectionists, the maximizers and the big picture thinkers.
Sometimes, the big picture can feel so big that deciding on a detail to start with can feel like a real challenge.
Back when I was in college, one of my lecturers had a strange rule. He didn't allow artists to draw until they had scribbled all over a full sheet of paper. He realized that when his students started their work with the big picture alone, they would be timid in their lines. Their lines would be soft, and ‘furry’. Their progress would be slow and unsure.
By scribbling across a sheet of paper before getting started, artists loosened up. They would use their tools with confidence.
