Anger channelization

Some wise men said that  friendship can be done with a person who is less or more capable than you but always make enemy is at least 10 times more powerful than you.
The reason behind is that if your enemy is more powerful than you so to overcome him and to prove yourself more worthy first you will make yourself at his level.
In this way you have already raised your level. Now it will be turn to prove ahead of him you will anything possible to win.
So in cover of revenge you have already raised yourself at your peak which your friend cannot do. 
A friend can only motivate you, support you but he cannot give that kick which is required to get your zenith.
According to my experience take taunts and negative comments about you as gifts and channelize your whole anger and frustrations in a positive way.
Prove yourself that you are worthy and can do anything.
