Have you made mistakes?  Sure you have, probably many.  Have you hurt others and have they hurt you?  Of course, that comes with being human.  Do you have past regrets?  Don't we all?  Now STOP beating yourself up over it.

You and I must stop living in the past.  I am so guilty of this, I bet you are too.  We have to stop allowing memories and events of the past, from robbing us of the present.

Let's you and I make an agreement with each other.  From this very moment on, let's make the past...the past.
