1. Some things just are. They just really are. Detaching from the fact that I have more control than it exists.

But unlike the Stoics, it would cause the natural cause-and-effect- Determinism that is associated with such a thing, and thinking that one can resist things out of their control is quite ridiculous, especially since those things are likely the things that would last the longest.

Nothing more, but nothing less than actual pain neither.
