Constantly

The emotional pendulum of a developer's self-worth oscillates faster than a metronome on cocaine. One moment you're architecting a beautiful solution with perfect abstractions, feeling like you've just invented the next React. Five minutes later, you're staring at a semicolon you forgot for 45 minutes, questioning every life choice that led you to this career.

The metronome perfectly captures this bipolar relationship we have with our own competence. It's not a daily thing—it's a *per-function* thing. Write an elegant one-liner? God mode. Spend 3 hours debugging only to realize you were modifying a copy instead of a reference? Existential crisis. The frequency of this swing is what makes it so relatable—it's not occasional imposter syndrome, it's a constant back-and-forth that happens multiple times per coding session.
