In looking for humor, keep in mind this guideline: Sometimes it takes a little time to see the humor in your upsets; you may not find something to laugh about immediately.
In every job, relationship, or life situation there is inevitably some turbulence. Learn to laugh at it. It is part of what you do and who you are.
