Idle.

“Boredom is the root of all evil – the despairing refusal to be oneself.”
— Søren Kierkegaard

“Idleness, we are accustomed to say, is the root of all evil. To prevent this evil, work is recommended…. Idleness as such is by no means a root of evil; on the contrary, it is truly a divine life, if one is not bored….”
— Søren Kierkegaard (Either/Or: A Fragment of Life)
