I thought of an even better analogy. Lets take our beloved dogs. You know how hopelessly devoted they are to their masters. I mean theres not more worshipful animal that mans best friend. Now, we can use a leash and our dogs follow us explicitly. Or, as with the horses, we can use not leash. Now, dogs are more devoted, trainable, and leadable. They will follow us somewhat better without a leash. But, say youve got two or three following you, one a little older and wiser who will follow you diligently to the desire destination, one young and easily distracted. Hell follow a bit, but then hell see a little butterfly fluttering around and run after if for a bit. Then, hell look up and noticed that he almost lost you completely, and run like the dickens to catch up. This pattern will probably recur a few times until the destination is reached. Then, you may have a completely distracted, lazy, stubborn old hound whos just going to do his thing. Heck, he might just plop down and say forget that, thats too long and too hard of a trek. However, you as the leader did not waiver, did not change paths or directions. You were on course and true for allow dogs following you.
