Answer to Question 1
Burnout may be the result of unrelenting stress, but it isn't the same as too much stress. Stress involves too many pressures that demand too much of you physically and psychologically. Stressed people imagine that if they could just get everything under control, they would feel better. Burnout, on the other hand, is about not having enough. Being burned out means feeling empty, devoid of motivation, and beyond caring. People experiencing burnout often don't see any hope of positive change in their situations. If excessive stress is like drowning in responsibilities, burnout is being all dried up.
Answer to Question 2
Engaged or enthusiastic workers are the happiest in their jobs. They take pleasure in and are challenged by jobs where they can use their skills and energy. They identify with their work and the organization they work for. Those scoring high in work engagement exhibit a persistent, positive state of fulfillment; vigor (high levels of energy and mental resilience while working); dedication (being strongly involved in their work); and absorption (highly engrossed in their work).
