Drawing with thick markers makes it hard to draw small details. But, often when brainstorming on paper, I would find myself using the same pen regardless of what level of detail I was hoping to explore. Inevitably, my inner skeptic would tempt me to elaborate on details that could have waited; and, because each of these diversions made progress harder, I wanted to find a way to limit them.
As an experiment, I started drawing with thicker markers when thinking through abstract concepts so I could only sketch large shapes and short phrases. And, it worked! I had no choice but to stay focused on the forest rather than the trees.
The tools you use define your creative process. So, think about what you're trying to accomplish and then be deliberate about using the right tools to get you there.
