The guardian at the gateway to your mind

Posting from Lew Smallwood's blog:
There is a guardian standing guard at the gateway to your mind? It’s called your reticular activating system or RAS, which is the scientific term for a network of nerve pathways situated at the base of your brain that connects the spinal cord, cerebellum, and cerebrum, and acts as a filter for all the sensory input your brain draws from your external world. Reticular, from the Latin word for ‘little net’ simply means a netlike structure. Everything you see, hear, touch, taste, or smell passes through this fine network, which then relays the signal to the appropriate part of your brain for processing.
You can think of this system as something like Google. When you type a word or search string into Google, it scours the internet for everything it can find that relates to that specific phrase, retrieves it and presents it to you, and it does this in a matter of seconds. Your reticular formation does much the same thing but does its work in thousandths of a second.
The inherent danger for us whenever a failure or disappointment occurs in life is that we can identify with it too closely, and therefore mistake the failure for ourselves. That can lead to adopting a mindset of ‘I failed therefore I am a failure’ and that dominant thought attracts further failure images and messages.
It is better to forget the failure and focus on future success. That mindset will attract positive images and messages. Never label lack of success as failure, simply learn from it and be grateful for the lesson the set back provides, and keep you RAS set for success.
Just change what you think about, change your dominant thoughts. Because in life you eventually attract what you think about most of the time.
