Who are you inside!

Who are you inside,
The boy or the man.
The skin or the tan,
The leader or the fan.
What is your worth,
A coal or a diamond.
A borrower or a fund.
A silence or a sound.
Why do you live,
Jumping like a fallen pin.
Smiling like a healing kin,
Trembling due to fear within,
Who are you inside,
The extrovert or the introvert.
