Establish your own Guilt
Having expeienced quite the display at a Taxi rank here in Sydney the other night, I found this post; Offend Yourself Sometimes, by Marcel Wichmann quite instructive.
While I try and absorb the sentiment in the following line for myself, I've adjusted the wording in order to help me make sense of the behaviour of Sydney Taxi Driver #8168:
Our egos make us defensive. Whether it’s defending from others or from ourselves, if it’s something we should confront, this defensiveness blocks us from improving.
Note this defensiveness in your everyday encounters and improve by figuring out what you would do differently, if it was you.
