Are you able to recognize the early signs of burnout in yourself?

Unfortunately, stage 1 of burnout is the honeymoon stage. It's where you're so excited about your new venture (work, project, etc) that you don't mind the stress and long hours. Stage 2 is the speedbump stage. That's when you start to burnout but still try to keep up the energy you put in while in stage 1. Some people recognize this and some keep going and end up in the final stage of burnout - exhaustion.
