On the Brightside lyrics

I met a man of 2 feet tall.
This man was quite ambitious
In a world that is so vicious
To us all.
I said "hi."
As he replied, he said
"Listen to these words that I have lived by my whole life."

You're only as tall
As your heart will let you be.
And you're only as small
As the world will make you seem.
And when the going gets rough,
And you feel like you may fall,
Just look on the bright side;
You're roughly six feet tall.

I met a man of 12 feet tall.
He towered like a giant
In a world that was defiant of his height.
I said "hi"
As he replied, he said,
"Listen to these words that I have dreaded my whole life."

You're only as tall
As your heart will let you be.
And you're only as small
As the world will make you seem.
And when the going gets rough,
And you feel like you may fall,
Just look on the bright side;
You're roughly six feet tall.

I am a man of 6 feet tall.
Just looking for some answers
In a world that answers none
Of them at all.
I'll say "hi."
But not reply to the letters that you write
Because I found some peace of mind.

Cause I'm only as tall
As my heart will let me be.
And I'm only as small
As the world will make me seem.
When the going gets rough,
And I feel like I may fall,
I'll look on the brightside;
I'm roughly six feet tall.
