. . . you'll find that being a friend is to like a person for who they are, even the parts you don't understand. You don't have to understand, or do the same, or live their lives for them. If you truly care for them, then you want them to be who they are; that was why you liked them in the first place.
In your training, do not be in a hurry, for it takes a minimum of ten years to master the basics and advance to the first rung. Never think of yourself as an all-knowing, perfected master; you must continue to train daily with your friends and students and progress together in the Art of Peace.
