Is the Default Mode of the Brain to Suffer?
Yes. Dissatisfaction is the source of productivity, and that's all our bodies care about. If someone were 100% satisfied with everything around them, there would be no reason for them to move or change anything. The ideal state for survival is just above depression. Happiness and pleasure are directional guides, "purposely" ephemeral so that we can get back to work distancing ourselves from death. Max Buddha would mean sitting until death, with no dissatisfaction for lack of nutrients or air or self actualization. Still the pursuit of this peace is extremely worthwhile because left unchecked, our dissatisfaction grows out of control, over-optimizing ruthless survival in place of contentment. Don't feel guilty for not being in a constant state of euphoria (looking at you west-coasters :-D), this is our lot as humans.That's how I see it.
