We are familiar with the scales of justice, but what about the scales of attention? Few of us analyze what our brain spends its time processing; we respond to stimulus, which is easier, and allows us to reserve more of our thought process for ourselves. As a result, life is not tiring at all because we are only halfway awake.
For those who study the brain, informally (which is better above 120) or formally (better below 120 IQ points), it becomes clear that mental state is a zero-sum game. During any span of time, the brain can process only so much, and so adopting more of one thing over others displaces those others. This leads to several interesting revelations:
Essentially, the more that we focus on our selves in the here and now, the more we miss out on what life is about beyond the self. This leads us into a condition called solipsism, where we believe that our minds are the world, and that the world therefore can be changed by intent alone, expressed through ideology.
The scales of attention show us that our consciousness is the ultimate resource. We can regulate our experience to make it more meaningful and more realistic, with the latter leading to the former because it filters out more of our own background hum of desires, impulses, emotions and reactions. But most of humanity will choose otherwise, which is why life in civilization (ideally) is a competition for who gets to clarity first, and can then lead the others.
