The Fighting Cocks & the Eagle (Aesop’s Fable) 

This Aesop fable teaches us that we should overcome our pride, be careful to never claim victory before it's certain.
A wise and a generous Enemy will make modest use of a Victory.
Get rid of the pride and ego. Pride manifests itself by belittling others, showing superiority, emphasizing, criticizing, mocking, elevating oneself, but not because one really is truly special and superior to others but only because the current situation has allowed it.
the world and often leads driven by pride leads to the premature celebration of the battles we have already lost.
