Cause

I used to have a cause
Now I'm not sure that I do
I used to save the world
Now I don't know where I'm going to

When I saved the day
Then children were free to play
But now the kids are gone
And I'm still here

What does a solider do
When his war is over
The mission is won
There's no one left to save but me

But I don't know how to save myself
I don't know where to start
I used to be the strongest
Now I'm lost
