Although One can change for the better, but there is always something that One cant change.
No matter how much One tries to change or to hide, One can never change the nature of One has born with.

When One is born to be a fighter, One is Always a fighter, for One is not born to be a follower.
Even when one tries to suppress the competitive nature, there will b a day when the competitive nature will surface once again.

Just be what you are, without hurting anyone or yourself.
