Idea

https://goo.gl/VobLMG

I look for her, but where is she?
Is she hiding away behind that tree?
But the oak can't hide her
'cause she's too bright!
And yet, I can't find her
'cause she's too shy!

Last time she came, she was early gone
Before I could play her my little song
But I can't stop thinking
'cause she's in my every cell!
And yet, I can't hear her
Well, I couldn't tell!

You might be musing: oh, what's her name?
I call her idea, and she's insane
But when she comes back,
she'll help me through!
Hey, hey Idea! I'm calling
Out to you!
