I fear the boredom that comes with not learning and not taking chances.

Boredom is... a vital problem for the moralist since half the sins of mankind are caused by the fear of it.

Boredom is the dream bird that hatches the egg of experience. A rustling in the leaves drives him away.

It is the unknown that excites the ardor of scholars who in the known alone would shrivel up with boredom.

This is the curse of our age even the strangest aberrations are no cure for boredom.
