Your patterns have been running for so long that your brain sees no reason to bring attention to them anymore. You have thousands of beliefs running in the back of your mind and they are controlling every aspect of your life without you even realizing it.
In order to become truly free however, you need to give up your current interpretations of the world. You don't need to give them up permanently, you just need to be willing to accept that they are really just subjective interpretations you have made and that they are not necessarily true. You need to be willing to look inside yourself and be honest. When you realize that your beliefs have been running most of your life, it can be a pretty overwhelming experience. At this point it is important to continue the awareness process by contemplating where your beliefs come from to begin with. It gets really interesting when you find out that the majority of your beliefs weren't chosen consciously. In fact, most of them were created through your upbringing.
Your whole upbringing was nothing but a formation of beliefs and, while you learned a lot of things that are useful in your life, you also learned many constructs that are currently causing you to suffer. Often times the beliefs that are currently controlling large parts of our lives started with rather insignificant events/thoughts that continued getting reinforced. We humans have the ability to take a very small event, interpret it, create an entire world around it and then carry it around with us everywhere we go. What most people don't understand however, is that when you do this, you are no longer carrying around the actual event as it took place.
