Hot boredom, he said, is a restless, impatient, I-want-to-get-out of here feeling. Along the spectrum of “hot boredom” and “soft boredom”, I believe there’s also an identifiable “lukewarm boredom” which expresses itself as “always having something to think about”. With “lukewarm boredom,” you don’t get the restless I-need-to-be-doing-something feeling, but your mind still needs to be continuously active.
