I think caffeine is often used for motivation during mundane tasks. Imagine working on a tedious engineering assignment like writing unit tests for a CRUD app. Over a few years it becomes a necessary lever, and at that point it is pretty close to an addiction.

Amount of caffeine consumed by a team may be an interesting proxy for how motivated employees are at a company (a small amount indicates high motivation, a medium amount indicates low motivation, and a high amount indicates either a severe lack of motivation or a high level of motivation).
