You must study to be frank with the world:frankness is the child of honesty and courage. Say just what you mean to do, on every occasion. If a friend asks a favor, you should grant it, if it is reasonable; if not, tell him plainly why you cannot. You would wrong him and wrong yourself by equivocation of any kind.
Never do a wrong thing to make a friend or keep one. The man who requires you to do so is dearly purchased at a sacrifice. Deal kindly but firmly with all your classmates. You will find it the policy which wears best. Above all, do not appear to others what you are not.
If you have any fault to find with any one, tell him, not others, of what you complain. There is no more dangerous experiment than that of undertaking to do one thing before a man's face and another behind his back. We should say and do nothing to the injury of any one. It is not only a matter of principle, but also the path of peace and hornor.
