Bridges and Trees

I had a wicked dream and it brought up a question,
If a new bridge was built, would I cross it?

It's not as simple as the question looks,
For the land I am on seems dreamy...

Yet I probably really didn't get much out of it.
Perhaps internal growth and stuff.

But with all that I invested in this land,
I still don't see any trees.

The people across the bridge are chanting,
And they've seen my hard work.

The people across the bridge are advertising,
Promising me the world if I do what I did here for them.

They're assuring me the best, but how can I be sure?
And how do I know the same promises weren't implied here?

My biggest thing is that while the trees might never grow,
Trees don't grow overnight...
