Practice Self Care
At the end of the day, we have to remember that we’re just human beings. If we want to maintain discipline over time, that means taking care of ourselves, and each other, as people who deserve things like rest, good food, and free time by virtue of being human. Thus, make some time in your schedule to get what you need in order to maintain your health and happiness. It’s a lot easier to maintain discipline when you’ve been sleeping and eating well than it is to keep going on fumes.
