Happiness is an inside job.

The line argues that happiness is primarily generated internally—through attitudes, values, and habits of mind—rather than delivered by possessions, status, or other people’s actions. Calling it an “inside job” borrows the language of work and responsibility: happiness is something one actively cultivates, not passively receives. The aphorism aligns with long-standing ethical and philosophical traditions (from Stoicism to modern self-help) that stress agency, reframing, and character as the foundations of well-being. It also serves as a corrective to the tendency to outsource contentment to changing external conditions, implying that durable happiness depends on inner practice.
