I think the most important rule is to always relax the mind and body. This rule ifs very important because if you do not relax you will not be ready for the next day. If u don't relax the mind you will have stress and sometimes depression. If this world and the people who lived in it did not relax this world would be chaotic. Every one would be depressed and sad.  We would not have time for are loved ones or friends. All we would be thinking about was how tired we are and how we hate life. We would be a big mess without relaxation. Thats why i think this is my rule. Everyone should relax. It doesn't  matter if you are the  president or a soldier because we all need to just relax.
