I once worked with a girl that was as chronic complainer. She also picked fights with the others in the office.
In the beginning she was cute and charming, but she quickly became very hard to be around. However, she was very good at her job. Her job was vital to the company, and without her doing her job as well as she did, my job would have been much more difficult.
I had to work to find a way to deal with the high energy and emotional draining that I had to go through with her. The way I found that I could deal with the situation was by appreciating what she did in her work. It is amazing what you can tolerate from some people when you learn to appreciate something about them.
If you have someone in your life that you find difficult to be around, take some time and find some good about that person,.
once you find the good, focus on it and soon you will see your entire relationship with them change for the better.
Remembering that there is something good in everything and everyone, use this affirmation to help yourself to stay aware of appreciating at least one good thing about all those around you.
