Bicycles change gears. Depending upon your strength, energy level, and the terrain, one gear works better than another. The same is true of our tools. You can't use a piece of technology without it also using some part of you. Just as pumping up a steep hill in a bicycle’s lowest gear would fatigue you, always using the highest-power tool can expose you to distractions that limit the depth of your focus on the contents of your notes.
