Separating your job from your ego is difficult but crucial for stress management.
Letting go of your expectations can put stress into perspective, even when you are the victim of other people's expectations (which you can't control).
Learning to go with the flow rather than resist what you have to do can help you be more productive and enjoy your work more.
Take care of yourself and pay attention to your own needs for less stress and better job performance.
You don't have to choose between your job and your life. Both will be more enjoyable and productive if they are balanced.
