The first time I watched it I didn't see the gorilla and was attending to the people in white and counting the passes. It demonstrated in a big way for me that there was a detriment in some cases that can be problematic. Sometimes I ask myself now what I was attending to and is or was there a "gorilla" in the room? What is the more generally beneficial belief for me going forward?
I also know that my perception of that video is permanently skewed because I anticipate seeing a gorilla. I concluded that for myself, my perceptions can be quite skewed not just with selective attention, but also perhaps more so, by anticipating an event/a reaction/a stresser or difficulty. I further concluded that for me it is largely unproductive and not generally beneficial for me to attend to such nuances unless or until there is a real and direct threat.
The brain gives us more of what it thinks we want to focus on. That was the beginning of the end of my depressive cycling.
