Literally for writing, but metaphorically in general. Discipline is the only way. Discipline does not mean one has to be austere; It implies clarity and fidelity about one’s goals. Discipline is deeply tied to affecting real change within oneself and to personal integrity.
Discipline, primarily, is our capacity to make a commitment in time.~ Robert Fripp from, https://austinkleon.substack.com/p/the-meaning-of-discipline
Motivation will get you out the door, but it fades over time. A good book or podcast might give you the momentary impulse to take your first steps along a path, but when the road gets tough only discipline will keep you moving forward.~ Dan Edwardes from, https://danedwardes.com/2020/11/17/motivation-is-temporary/
Without discipline I’m the pinball in the pachinko machine: I’m clearly directed (me by my goal, the pinball by gravity) but buffeted randomly (me by everything, the pinball by the pins) ending up in an uncontrolled final position. The critical thing to combine with discipline is ease. Not bashing, not self-loathing and certainly not self-violence. Ease within training.
