Forget Your Past / Forget Failure, Success
All your experiences in getting to this particular place are behind you. All the great things God did to get you here are behind you. They are of no value to you now, except that they can stand as an inspiration to help you go on.
The Apostle Paul said, "Forgetting the things that are behind." Did you ever stop to think what that man had to forget?
I believe (what) Paul meant (was) - (forget) both the successes and the failures. He wanted you to forget the failures because the blood of the Lord Jesus Christ has covered them; they don't exist anymore.
The only place they exist is in your mind - in those memory banks in your mind - and the devil will keep bringing them up and up again to bring you under condemnation if you don't renew that mind with the Word of God, and allow the Word to wash them out.
