No Trouble

I have built castles in the air
And I have built castles in the sand.
I have no trouble building castles
Except castles on the land.

I have dreams as large as oceans
And I have dreams as big as sky.
I have no trouble with dreaming
And I guess I'll be a dreamer 'til I die.

I am a man as large as a fly speck
And I'm no bigger than a minute.
I have no trouble with my biology
Except there's not much glory in it.
