People change for only 2 reason.

Wanting to be her true self or to wanting to be herself again.

Each & everyone of us is carrying a role. Daughter to the family, sister to a brother, employee of a company or a stranger to a stranger. As a newborn, we came into the world as a blank piece of paper. 

Those given to us were some genes that shape the most basic part of our body & its capacity.

Eg colour of the skin, the shape of our nose & possibly the max height that we can grow. 

There is also a thing call individuality, a distinct character we all carry when we were conceived. 

How well a person understand this individuality could varies. Some know it all along while some will require sometimes to figure it out.  

Something for everyone to ponder.
