a and r
Simple: Rest and relaxation. It's the only thing that can save you after a long day of being yelled at, being ignored, and being treated like a doormat.
I only had time for 10 minutes of R and R before my boss called me back to work.
After that presentation, I needed R and R just to remember my own name.
R and R is the only thing that keeps me from crying in front of my coworkers.
