A strong body makes the mind strong. As to the species of exercises I advise the gun. While this gives moderate exercise to the body it gives boldness enterprise and independence to the mind. Games played with the ball and others of that nature are too violent for the body and stamp no character on the mind. Let your gun therefore be your constant companion of your walks.
Americans in particular are myopic. They're not traveling as much. When you were a college student the next thing you would do on graduation was to take a year off and travel. That's what I did. I went to Indonesia.
