I started a new job a couple months ago after having worked double time for months at the last job. I tend to set tough/arbitrary deadlines for myself and then struggle to meet them. I throw myself into every job like its a startup and get very into it. I have a tendency to over-work. My new boss is aware of this. I get yelled at for working until 3AM. I am told to focus on a healthy balance. Everyone is encouraged to hit the office gym. I do so most days at 4PM, and it makes me more productive the rest of the day. Fruit for breakfast and vegetables are available for lunch daily. I work from home when I'm tired of sitting in my office chair. Since starting this job my resting heart rate is down from 95 to 72. And I'm more productive than I was at 80 hours a week and not taking care of myself. An unhealthy lifestyle is not efficient.
