Short and sweet, if you want a basic grasp of the fundamentals of Modern Stoic Philosophy, here it is:

  1. Control the things which are in your control.  Do not concern yourself with those things you cannot control.
  2. You gonna cowboy up, or just lie there and bleed?

There it is.

Yes, there is more–much more.  But that’s the short version–and probably the most important principles to grasp.
