There are several ways to avoid conflicts in your personal life and your professional life..
Here is one way~ Stop and think before you act or react. Did you know that Thomas Jefferson suggested; that one should count to ten when angry, and count to one hundred when very angry before you speak? You should try to think ahead and predict the consequences of your words or actions. Is my comment going to result in a conflict? Will my words result in hurting someone else? How do you react?
