The mind converts and changes every hindrance to its activity into an aid; and so that which is a hindrance is made a furtherance to an act, and that which is an obstacle on the road helps us on this road.
— Marcus Aurelius · Meditations

Our reading
An editorial interpretation.
A capable mind takes whatever stands in its way and puts it to work. What looked like a barrier becomes fuel for the action itself, and the obstacle turns into part of the route. The passage presents adversity as material for progress rather than a reason to stop.
