Selfish

What's it called when you only worry about yourself?
What's it called when you don't share your wealth?
I know what the word is.
And I'm here to tell you this.
I'm selfish.
I don't care about no one anymore.
What should I care for?
That nice guy act Is done for.
Nevermore.
My selfish acts are controlling me.
Some people call it slavery.
But I like it.
I feel brave.
So I'm happy to be its "slave"
I get what I want.
I do what I please.
If you don't like it..
Leave.
You think I'm really a slave for the selfishness, but I'm not.
Is it called slavery when you get what you want?
