Stress is of our own construct. You are your own prisoner. What active steps can you do at work to de-stress? Break them down in manageable action steps, some can delegate to other people, prioritize them on a to-do list.

How did this come about? What transpired prior, during and after the interaction with client? What did you learn from this? What would you have done differently if you had to do this all over?
