We live at by far the greatest time in human history. Those of us in the advanced world can listen to ANY SONG we want to at anytime. The same with most books and many movies. A city-dweller can order food, alcohol, cannabis, sex, candy, just about anything you can think of at pretty much any time of day. This is a tremendous danger to people who lack discipline.
Thankfully my own indiscipline largely extends to eating junk food, not exercising, and wasting time on Twitter. For many, the indiscipline starts with how you look at the world and what you expect to come from it. It’s better to expect nothing and seek to create that which you desire.
In this era of instant gratification, a lack of discipline can ruin your life. Whether it is poor habits of self-care or not adequately maintaining order around you. Indiscipline makes every problem worse.
