Why do you keep late nights? Is it to catch up with friends or family in person or over the phone? Is it to complete work? Is it to watch a movie or engage in some other similar entertainment? Or is it to spend time developing yourself through books and other means?
The night season is meant for sleep which is important to reset the mind and body but sometimes the mind and body find a type of strength in the purpose that one pursues such that it overrides the need for food and sleep in the course of a day.
Don’t be like the ones who are so driven that they use the late nights to get as far forward as they can at the expense of family, friends, conscience and peace.
What you yearn for or desire is really important and should be chosen carefully so that the night season of your sacrifice produces a great reward that will be satisfying to every part of your life and all who are in it.
