A really great story via Chabad.
It's so easy to complain and kvetch. It takes a few seconds more to compliment.
Always tell the boss...
"My mother told me that when she was a young working woman, sometimes someone would give her a nice compliment. She, of course, would reply: “Thank you.” But she always thought, “Tell my boss!” So when someone deserved commendation for a job well done, my mother made a practice of telling the boss."
