This sounds a little crazy but I think I work more efficiently when I'm stressed up than when I'm more relaxed. It sounds like a totally weird outcome as most would think that we would be able to think through issues/work more carefully when we are not hard pressed for time. But I find myself doing the opposite even though I logically would like to have more time and be less stressed. So strange. Looking back, it seems this trend has been manifesting itself since I was a student.
