"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."

This quote is saying that we should use our body, mind, and character as we make a journey to the real world. You cant really just automatically be liked you have to have character and mind. Be healthy and happy with yourself. Some of these things we need in mind for certain occasions. Your body, mind, and character is what you always need to have with you.
