An interesting question does three things: it surprises the other person, it invites a real answer (not a rehearsed one), and it reveals something meaningful. The best interesting questions don’t have obvious answers — they make someone pause and think, which creates a moment of genuine connection.
Boring questions have predictable answers. “What do you do?” gets a job title. But “What would you do if you didn’t have to worry about money?” gets a window into someone’s soul. That’s the difference.
