More than 70% of people spend more than one hour a day using a pen. Yet, we lose notes in our notebooks, take pictures of whiteboards, and don’t have the option to do equations or music composition with a keyboard. Writing is also a key part of the creative and learning process. Studies indicate students learn better by writing. For example, diagramming before solving a science problem can lead to 36% higher scores.
