I believe American’s overworking is a mix between motivation and just having too much work to do. Right now because I am young and new to the field, I enjoy being given tons of task and responsibilities. I end up working late because I am motivated to finish my projects so I can be assigned new ones. I would say I am very motivated to learn as much as I can in this field. When you work too many hours, it really gets to you and demotivates you from wanting to work. The best thing to do when you feel like your burned out is to take a moment and breath. Let your boss know and work with him/her. Your best work is done when you want to do it.
