To me those are good skills, but at the end of the day the important thing is to work in a way in which after going through a project (or after getting some rest in between projects), you have as much or more energy that before starting the project.
Discipline can be fine for 3 or 6 months to finish a very tough deadline, but if you go through 5 years of discipline where every day you are more tired that the previous day the quality of the work will suffer a lot.
