> You don't gain discipline by waking up earlier than necessary.

You absolutely do. Please take a second to actually lookup the definition of the word. It may not be added discipline in your life, but it is for many other people that don't live with the same daily habits as you. You don't get to change the definition of a word to fit your narrative, sorry.

The point is that waking early is not inherently a thing of discipline. You can no more judge one's discipline by one's waking time any more than you can judge one's discipline by whether or not they play an instrument every day. Both can be part of a disciplined life, but neither are actual markers of it. Neither are going to suddenly give one more discipline in their life just by doing that one thing. It isn't a magic cure. This is definitely not changing the definition one bit - you have already provided it.

You seem to have a New Age definition of what discipline is. There is no such thing as an "inherit discipline".

A marine, doctor, rock star, sanitation worker, train operator, and professional athlete are all going to have drastically different things they consider good discipline.

If I have a problem responding to text messages in a timely manner, I can improve my personal discipline by introducing a new habit to take 5 minutes before I go to bed to reply to every message. If I have a problem with my weight I can start going to the gym and change what I eat, discipling myself to take more care of my body. If I have a problem finishing projects, I can discipline myself to set realistic goals and expectations of what "complete" means so I can feel more confident ending things.

Changing behavior to achieve a goal (whether it's self-imposed or from your boss) is by its very nature achieved through discipline.
