"Every person must be ready to hear, be quick to talk and not get angry quickly." This is a principle that holds much wisdom.
Understanding is the ability to understand through knowledge, understanding helps you make the best decisions and the best decisions avoid future regrets. The beginning of this chain begins with the hearing, whenever we are engaging in conversations our instinct is to give our opinion and it fills us with pleasure to be heard by others, but the best sage is not the one who speaks much but the one who utters the right words to the right circumstances.
In the many words the error will never be absent, but even if the ignorant is silent he can pass as wise. So the first step to understanding our fellow human beings is to listen to them, analyze what they think, their concerns, everything they have to say even if we do not agree with them.
Once we have listened carefully and understood the other's point of view then we can look for the right words to answer, we can take enough time because once you say the words you can not return them.
You must be slow to bother yourself, it is a difficult virtue to acquire because generally when someone attacks us or even when something does not seem to us we act to defend it and it is not bad to defend ourselves, what is wrong is to do it under the effects of anger, because in the The wrath of men does not dwell in the justice of God.
When we act out of rage, everything we do will be with the intention of damaging, and we can do things that, even though we regret, we will not be able to remedy, offend your partner or your loved ones, even doing physical damage that will later bring bad consequences to your life, then, if you fall into a state of anger the best thing is not to make decisions, not to act. Relax and wait for the anger to pass, then you can make the best decisions.
