Even with therapy, to "know thyself" means to only know the tip of the iceberg. The more one attempts to know thyself, the more one can be an author of their own lives. Conflict will never cease however. We are, after all, human.
What I have learned in the last two weeks of working at a psychonalytic hospital:
People have many defenses. Humor is one such defense. Defenses protect against unwanted feelings. Unwanted feelings are basal, primal urges of lust and murder.
People are in constant conflict, guided by unconscious processes that have been projected to the present from the past in order to make sense of the world (minds are computational machines attempting to model and predict "what happens next"), a beautiful attempt at homeostasis.
The introduction of the internet into all facets of daily life, I think, has converted the shower into the sole container of deep thought. Boredom struggles to exist elsewhere, and boredom is the genesis of creation.
One of the most meaningful and sustaining things one can do with life -- volunteer time for someone else with the intent of improving circumstances (i.e. altruism) -- is inaccessible to many because "grindset" a.k.a. capitalism has commandeered attention just so one can survive.
