One tool I thought I might share because it seems both powerful and simple is the Elevator. Take some difficulty you are having (what they would call a pattern), such as procrastination, and form a question, such as “why do I procrastinate so often?” Then imagine you are standing before elevator doors, which open. You go in, and your question is written on an enormous button, which you push. The doors close and you go down for a while. Then the elevator stops, the doors open, and a scene is presented to you. Make a note of what that scene is. It is quite likely it will be from your childhood.
Do this 3 or so times, and then interact with the images intuitively and intellectually, and see what they are telling you. In my own experience, simply calling this content up helps relieve some of the behavior.
They teach other tools as well, but I thought I would share that one.
