Play the “I wonder” game
The next time you wave to a colleague and they appear to ignore you or someone pushes into the queue in front of you and you start to inwardly boil over, try playing “I wonder” instead of getting dragged into negative thinking.
Think of some different scenarios which may be going on in the other person’s life which may have caused the behaviour. “I wonder if she’s not feeling well and is in a hurry to get home” or “I wonder if he’s just had an argument and is oblivious to his surroundings” or “I wonder if she saw me”.
Purposely opening your mind to different possibilities and giving the person the benefit of the doubt will release you from the draining effects of negative thinking.
