"Of all the work that is done or that can be done for our country, the greatest is that of educating the BODY, the MIND, and above all the CHARACTER, giving spiritual and moral training to those who in a few years are themselves to decide the destinies of the nation" ~Theodore Roosevelt

What is trying to tell us is that in order to become a good country is that we need to change our personality and become united not separated. Our body means to change our body language and become more active. Character means that we need to more polite to one another. Spiritual means be more open to each other. For example make this country who and what you want it to be. And if we all work together then we might be close to being perfect. And by the hard work you do now will be resulted by tomorrow.
