その言葉の意味を見つけ,

You know that life is like an old steam engine,
you can either go ahead, or in reverse
Now the road ahead may look pretty rocky,
but the road behind is bound to be worse
If you close your eyes you won't see the sunshine
if you plug your ears you won't hear a thing
And if you shut your heart you'll shut out

​
