The end for self-discipline is personal improvement; the end for discipline lies beyond the self. This distinction helps explain why individuals can be incredibly self-disciplined and yet see very little external achievement as a result. Sure, they never miss a day writing in their journal and never lose their temper, but those displays of self-mastery don’t automatically lead to outward success.~ Brett McKay from, https://www.artofmanliness.com/character/behavior/are-you-disciplined-or-just-self-disciplined/
There are lots of ways to talk about this distinction; the particular way described by McKay comes from an author he’s interviewed. I’d never thought about is as “discipline” versus “self-discipline.” I’d always thought of discipline as a thing, and then the “self-” prefix in “self-discipline” means that thing done to myself. And I’m not going to change how I use the words, “discipline,” and “self-discipline.” I see why they’re using “discipline” and “self-discipline.” I think I’d prefer to use, “inward-directed,” and, “outward-directed,” discipline. Everything I do to myself is self-discipline, but when my goal is to change myself, then it’s “inward-directed,” and when my goal is to change the world, then it’s “outward-directed.”
But the point of the distinction is very interesting. Do I actually have goals which are the, “why?” behind my self-discipline? Are those goals an appropriate mixture of inward- and outward-directed?
