Do you say things that a future more mature, enlightened and experienced you would wish he/she did not say?
It’s inevitable I guess. We say things we swear are true, only to mature and change our mind.
If you are self-aware, when you feel some emotional self-righteous outburst coming on, you will pay attention to the little voice inside that says “maybe I am wrong” or “I really don’t know a lot about it and need to get the whole picture”.
This can avoid embarrassment and loss of credibility for you.
None of us know everything. And our knowledge is from our point of view and our experience, which is unique to us.
Ask questions first, or instead.
