Complaints As A Tool

Complaints Have No Magic by Tina Roth Eisenberg:

Thank you for these magical words, Cleo Wade. This was one of my biggest energetic shifts, when moving to New York City, 20 years ago, realizing people don’t really complain here much. Complaining is draining. It truly has no magic. Hence my personal rule: “When I catch myself complaining about something repeatedly, I have two options: Do something about it or let it go.”
A complaint is a tool.
A complaint for the sake of complaining is wasted energy. A complaint as constructive criticism or with solution(s) adds value. To say one won’t complain means one will not effect change. How does that add value?
