We all say things that we later regret. It’s really about slowing the brain down a bit to think before you speak.
Remember, Silence is Golden.
Practice makes perfect and you are a good, honorable person to acknowledge that when you speak you sometimes get it wrong.
Another thing you could do is apologise if you have the opportunity. Sometimes as soon as the words come out you can regret them in which case you could say….”I’m sorry that was out of order, let me rephrase that”. You will find in doing so people will listen to what you say as oppose to thinking badly of you later.
