It is very simple and anyone can try this. It is common that when we talk to children we talk in a polite way and mostly we try to give them the right and positive direction in whatever they are experiencing at that time. When we talk to our colleagues and co-workers, we talk in a way that they can accept what we are trying to deliver. When we talk to our friends, we use a specific language in which our friends enjoy listening to us and being with us. When we talk to our neighbors, we greet them and give them smile before we start talking to them respectfully.
It is all about appreciating other with gratitude and positivity and in return people accept you and like to talk to you and to be with you.
You can try it anytime. You only need to be intentionally expressing positivity with all those whom you meet with all day long and you will feel the difference within no time.
I know there are things that create negativity in your life, in your mind and all around the environment you live in but then this is the challenge to deliver the positivity and bury all the negative vibe into deep within.
