On the brightside

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.

Your only as tall
As your heart will let you be
And your 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
