We’re becoming an undisciplined people …
I'd say exercising self-control is very important for a dissolute life.
Many men and women in the world demonstrate great willpower and self-discipline in overcoming bad habits and the weaknesses of the flesh.
Work while you work, play while you play - this is a basic rule of repressive self-discipline.
The only discipline that lasts is self-discipline.
I'm a very, very disciplined person.
If I'm running on my own, no one's holding me accountable, so I will stop and walk.
Mentally, I am quite good at self discipline.
