"If the child has not an object that it can occupy itself with, it feels ennui; for it does not yet know how to occupy itself with itself."

Next Quote

I do not care for anything. I do not care to ride, for the exercise is too violent. I do not care to walk, walking is too strenuous. I do not care to lie down, for I should either have to remain lying, and I do not care to do that, or I should have to get up again, and I do not care to do that either. Summa summarum: I do not care at all.

— Soren Kierkegaard
