How Do You Do It

How do you start when you know it’s gonna end?
How do you wait, if you never plan ahead?
How do you laugh when you see what makes you cry?
How do you sleep at night when you know you’re gonna die?
How do you do it?
How do you love when you know I’m gonna leave?
How do you walk around and believe all that you see?
I know you’re sure, I know you made up your mind
I won’t be next to you, but there’s gonna be a line
How do you do it?
It’s all been written down in stone
Not by a man, but by a code
This thing is built so that it’s always gonna fail
So how do you climb aboard when it’s flying off the rails?
How do you do it?
