He who fights with monsters might take care lest he thereby become a monster. Is not life a hundred times too short for us to bore ourselves?

Is life not a thousand times too short for us to bore ourselves?

Battle not with monsters lest ye become a monster and if you gaze into the abyss the abyss gazes into you.

Whoever fights monsters should see to it that in the process he doesn't become a monster

Whoever fights monsters should see to it that in the process he does not become a monster. And if you gaze long enough into an abyss, the abyss will gaze back into you.

I have no family to take care of.
