Unwatered Trees

I thought I had an idea
I realized I did
I threw my idea out the window
And it grew into a tree
No one ever saw the tree
But I'm sure it grew really big
Cause every time I'd think of it
Man it sure seemed big
I'm tired now and that's what happens
When your nurturing a kid
But everyone knows as well as I
It's nothing like a kid
Just a thought that could have been
or would of never been
So here I give it up to you
Cause that's all I really do
If you want a good idea
I'm the best there's ever been
I'm the best at humm
Quitting on my dreams
