Well stated! So well stated, in fact, I've added your quote to my drills resource page (under "why do drills").I believe there are several different ways to look at drills.
First off, I think you can look at drills as an end in themselves. Work the drills and learn variations on a standard -- maybe like playing "Chop Sticks" on a piano. A drill can show you how minor riffs can produce divergent outcomes -- selection of speed and spin all dramatically changing what the balls will do on any given shot -- similar but different.
Second, some people need a little structure to maintain their interest while practicing. IOW, the drill is an overt tool to help maintain focus. One guy likes the treadmill, the other likes an outdoor run. One guy can practice 9ball or 14.1, the other likes drills, but they want both want the benefits of the exercise. And for these folks, drills are a great little game of solitaire to strive and measure their performance against.
Personally, I think the most valuable way to look at drills is like a Zen koan. The drill is just a vehicle to get you inside your game, your mechanics, your stroke, your mind. This is also the toughest way to workout. You are not only working on the aggregate shots and required positional plays of the drill, you are also seeking to achieve a mental state wherein you can become introspective about your choices, mechanics, and stroke. There's the real payoff.
