Well there are ways to calm down. Cancel out the external. If not the external then it must be you. Your breathing too fast saying off the wall things. No. That is not the right way maybe you are excited for whatever reason.
I will give this secret of mine away. Breathe with decision. Before you encounter anybody or go out into any restaurant. Simply check your breaths slow calculation. You will find that you will be able to ignore toxic blah blahs who have their mouths on free run. Lord knows it aint wise. Lord says lets the fool be s fool before you. While your watching how you breathe and carefully watching how you say the words, be a man of few words, but lord knows when its time for you to talk it will be wisdom. And not some gassed out sentence. This technique has prevented me from saying blatant foolish things. When you speak so doesyour heart, and we want our hearts calm,extend your arm out is it shaky? You want solid control never shaky. Bad decisions arouse from jittery panicky type behavior well there is my well thought wisdom. Took me 12 years to here buti am here and i only progress.
