捨己 is a Chinese and Japanese word that means selfless, self-sacrifice (to help others), self-renunciation, or altruism.

獻身 is used to describe being so devoted to something that you will make sacrifices for that goal/thing/person.

You can also translate this word as any of the following:

This can be a dedication to or for someone but is often used as a dedication or making sacrifices for your country, public service, or a cause. For instance, an Olympic athlete makes great sacrifices to train in his/her sport for their country and compatriots.

紀律 is a Chinese and Korean word that conveys the idea of extreme self-control and perhaps self-sacrifice, and obedience.

This word matches the kind of “discipline” I was in the Marine Corps. There is also an additional idea of maintaining order or being orderly in your tasks.

This idea would also fit an athlete training for the Olympics who gives up many pleasures to stay focused on their training.
