If your stress comes from job insecurity, take stock of yourself. Update your resume, and remind yourself of your skills and strengths. Also, make sure you keep up with new developments in your field. To help your workday go smoothly, try pacing your activities: Do more demanding work in the morning, when your energy level is higher, and easier work later in the day, when you may be tired. Take breaks throughout the day. It will help clear your mind and relieve pressure.
