Tim Ferriss frames low mood not as a standalone condition but as a downstream symptom of a recognizable cascade: anxious rumination leads to sleep compromise, which leads to increased caffeine, which further degrades sleep, and after 3-4 days depressive symptoms appear. This causal chain reframes depression from something mysterious into something predictable and therefore interceptable. The lever isn't mood itself—it's the sleep hygiene upstream of it.
