The right pace leaves room to notice where you are going.
You can move so quickly that every inconvenience becomes an obstacle to the route you already chose. A recurring frustration might deserve investigation. At speed, it becomes one more thing to push through without asking what it is telling you.
A sustainable pace leaves enough attention to notice changes in the work, in other people, and in yourself. Slower is not automatically wiser. But a pace that prevents all reconsideration can carry you efficiently past the place where you needed to turn.
What have you been moving too quickly to reconsider?
