Your work-life is only one area where self-discipline comes into play. If you are content with just earning enough money for living, that's fine. I agree with you on that.
But a lack of self-discipline might hurt you in areas which are much more serious.
If you keep avoiding hard talks with your spouse, eventually you will have a problem.
If you do projects or activities with friends and always shy away from the unpleasant or dirty work, you're not being a friend they can trust to really go the extra mile with them. You will lose good friends over this. I personally have grieved a good friend over this.
If you never put any planning and execution effort into your family activities, there won't be any.
If you always keep away from doing mundane things like dentist visits, grocery shopping, regular house cleaning, your kids will suffer for your laziness.
And, maybe the worst: If your kids happen to not be overly gifted easy-achievers, and you do not teach your kids that most goods things have to worked hard for, then you have denied them a lesson their future life will depend on.
