Du bist die Aufgabe. Kein Schüler weit und breit.
This is one of a series of aphorisms written by Franz Kafka in 1917-18. An Aufgabe is an assignment given by a teacher as a problem to be solved by a student. But in this case
You are the problem and there is no student available (or able?) to solve you.
Who made you a problem, a task to be done, a mission to be accomplished?
Can a problem solve itself?
