Introspection can frustrate and define

You don't know what you've got until you lose it
You don't know what's right without the wrong
You don't know what you'll miss out on 'til you blow it
And by then what's right is over and it's gone.

You can't move on until you've faced the past
You can't mature 'til you realize not all can last
You can't become anew until you've faced the pain
And only then true happiness can you attain.
