Hold you breath, and count to ten before saying anything to a certain person.
When you need to talk to someone, think of what are you going to say for them. Because words if go out of your mouth, it will not come back again, it could hurt them, if you say something wrong, even you don’t mean that, but people don’t understand that you said that spontaneously. So it will be there passive consequences over you, words could break bones more than sticks and stones!
Finally, we are responsible of what we say, we have to be aware in selecting the word before uttering it.
