"Instructors should teach people exercises such as they can practise at any time after leaving their instructor. Instead of riding about in the pointless way that so many people do, by means of these exercises the instructed rider can always be improving himself because he will always have an object. It is the practice which follows instruction that eventually gives satisfactory results and produces the finished horseman."
