Inxs - Questions letra de canción

How do you know when it's time for you to go
How can you stop when you don't know how to start
How can you go back when you don't know why you're here
How can you see when your eyes begin to fade
How will you hear when you've heard it all before
How do you do all the things you want to do
How much can you take when you've taken all you can
How can you act when you've never seen the script
How can you choose when you don't know which is right
