Leaders must maintain order in there land. Three of the most sufficient ways to maintain order are discipline, public appearance, and security. It's important to keep order in a sufficient way, because if you don't your land, home or class room will be full of chaos and turmoil.

Discipline not only shows that you have the power or authority to punish people, but it also teaches citizens, offspring, or students that if they commit a crime, not do there chores, or cheat on a test that it comes with a price. If they learn that then they won't do it and it will keep your empire, class room, or home out of turmoil. Public appearance allows you to give a good example towards your subjects. It also shows (if your a king or president) that you also have to pay your taxes, drop your kids off, obey the law ect. If they know you have to do all of this too then so will they. And most importantly security. Your subjects need to know that you have everything under control. It's not a matter of alarms and sensers it's about peace of mind and trust. One major thing people worry about today is if our country will go even more into chaos then it already is. Good public appearances help this, such as some by Obama with him talking about how to clean up this mess with proof that we can gives us peace of mind.

These three things are very important in empires, homes and of course class rooms.
