I guess.

“I like to think of fire held in a man’s hand. Fire, a dangerous force, tamed at his fingertips. I often wonder about the hours when a man sits alone, watching the smoke of a cigarette, thinking. I wonder what great things have come from such hours. When a man thinks, there is a spot of fire alive in his mind–and it is proper that he should have the burning point of a cigarette as his one expression.”

― Ayn Rand, Atlas Shrugged
