Painting with a Series

Doing a full series can take a great deal of energy and time. By "series," I mean several paintings -- say, six or more -- that deal with a particular theme. The idea is that you keep all variables the same. This includes the choice of pigments, the dimensions of the canvas, the method of applying pigment, and, of course, the subject. This forces you to focus on developing your vision and not on your tools. You can really grow as an artist this way.
