You can't look forward to anything if you keep looking back in the past. You can't move past it until you leave it in the past. Learn what you need to from it then JUST FLUSH IT out of your mind so you can move forward.
To see clearly where you need to go, you have to clear your mind so you have ROOM to figure it out. Don't CLOG yourself up with thoughts of what has happened in the past.
You already know what happened you don't have to keep RELIVING IT. JUST FLUSH IT so you can move on. You can't stop the thoughts from popping up trying to GRAB YOUR ATTENTION but you can JUST FLUSH IT at a quick glance so you don't have to relive it.
If you want to be able to look forward to what the future holds for you, don't let the past hold you back. JUST FLUSH IT out of your mind so you can get moving.
