Wait for your rational mind to return
when emotions are getting the best of you.
Rule of Sevens
Do not interact with others - especially to try and resolve conflict - when you are agitated.
Notice the feeling rising inside of you. Then wait seven seconds.
Wait seven minutes.
Still annoyed? Wait seven hours.
Then, if need be, seven days and seven weeks even.
Do eventually discuss the instigating event, but do not try to do so while you are still upset about it.
