Before you know it, you're feeling tired, cranky, and downright awful. These are some of the classic signs of burnout. In today's 24/7 society, it can be hard to resist working around the clock, especially if you are trying to get ahead in your career. However, if you want to avoid completely burning out, you need to make sure to take mental breaks now and again to help keep you feeling refreshed.
