Educating the body,
                      Mind, and character    
                                                                                                                    "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 few years are themselves to decide the destiny of the nation 
  
- Theodore Roosevelt    

 What i understand about this quote is that you need to educate your body and character in order to do good for your country. you must train other in giving moral training for those who are going to choose the faith of this country. An hope that they will choose the right for this country to live. An example would be that you need to choose whats best for you and everyone around you. Like a class president what choose the best for his class. That's what Mr. Roosevelt wants.
