I am the strongest

All of us have heard one day from a person that he thinks that she estimates that no one can be superior than him.
It's absurd but let's examin the reasons :
-The most evident one is education, family Perhaps he was educated in an environment where the motto is we are right, we can't afford someone to disagree with us in order that our weaknesses aren't highlighted.
As a result the children begin to imitate their parents, they don't want to share their toys, they begin to impose their laws in an agressive way.
I advice people like this to try step by step to be open minded and to accept that they won't succeed like this, success comes from the success of others ans from the feeling that everyone is unique and has his strenghts.
Wake up strongest people, it's not a shame you need practice, especially imitate your opposite.
It'sn't late, act begin the change.
