Spotted Soul

My sister’s soul was spotless, mine was spotted by design

They were hues of different colors

That did not fall in line

I was angry, I was crazy, I was shouting all the time

And when my family saw me

They wondered why my sister was so benign.

I hoped that I would change, could change

Into something more respected

And in that quest for glory,

I lost all of my perspective

I forgot the most important thing

About self-respect

Is the four letters

S-e-l-f

Who am I?
