Never close those doors
Before you're sure it's right
Always look to the future
But don't forget the past
Each bridge you cross over
Must be left not destroyed
You never really know when
Retreat will be all you have
Look back over your shoulder
Now and then to reassure yourself
You made the choices that are right
For the walk in life you need now
Never let go of memories
For they may be all you hold
