Stephen King

“With a wry smile, he went on to hypothesize more generally—and, I suspect, only half-jokingly—that addicts are bored or frustrated problem-solvers who instinctively contrive Houdini-like situations from which to disentangle themselves when no other challenge happens to present itself. The drug becomes the reward when they succeed and the consolation prize when they fail.”
― Anna Lembke, Dopamine Nation: Finding Balance in the Age of Indulgence
