Artists begin without being asked. That is the acid test of agency: not just having ideas, but acting on them. Where experimenters may carefully calculate need, passion, and resources, artists supply all three themselves. The need and passion are internally generated. The resources are ideas and time, but time is not infinite. So choosing one subject means abandoning the rest, with no guarantee that the choice is right. The only way to find out is to start. Almost every artist describes their way of working as a curious combination of invention, which is conscious, and discovery, which is not.
