That's like saying I'm lazy because I prefer sometimes doing a dance class over just running on the treadmill.

There's more than one way to do things. That said, drills are important. You do have to practice at some point. But if it's the -only- thing that's used, as it is in some classes I've taken, it's boring and harder to retain the information. And in my personal experience, I've seen that sticking with -only- that method can sometimes be counterproductive. It's avoiding the depth of understanding needed for actually applying the math.
