This is a method that I used to get rid of this not-so-healthy habit of mine. Many artists have and still do suffer from this in their artwork. To get rid of it, I started with side-view faces and drawing random squiggles that would represent different parts of the face, such as the glabella, the nose, the lips, and the chin. Then I just filled it in; Slowly, of course, to make sure each face had variety. And then rinse-and-repeat but at a faster pace.
